I’ve found a desperate guy (Daniel Pistelli) who didn’t give up at the windows error dialog:

Time Travel: Running Python 3.7 on XP

I like how he approaches the topic:

If we try to start any new application on XP, we’ll get an error
message informing us that it is not a valid Win32 application. This
happens because of some fields in the Optional Header of the Portable
Executable.

[…]

Fortunately, it’s enough to adjust the fields in the executable we want to start (python.exe), there’s no need to adjust the DLLs as well. If we try run the application now, we’ll get an error message due to a missing API in kernel32. So let’s turn our attention to the imports.

And then he goes on for another 5-6 screens. To sum it up, apparently you’ll have to:

  • Modify the python.exe header,
  • Run a tiny Python script to remap some DLL calls,
  • Recalculate some binary hashes,
  • Create a fake kernel32.dll with certain calls forwarded,
  • Modify python37.dll to point to this fake thing,

and then you’re all set. To be honest I couldn’t quite follow (let alone verify!) some of the steps but it looks legit and there are links with Daniel’s half-baked solutions for the harder parts, also a lot of Python sources explained. I will definitely give this thing a try.

In fact, here are the final scripts from his GitHub page:
https://github.com/dpistelli/xptmrt

Moral of the story: you can be crazy, but you’ll never be dismantle-all-dlls-and-exes-and-open-hexeditors-and-disassemble-hashing-algorithms-and-mock-it-all-together-so-it-works-under-xp-crazy!

This document aims to give an overview of Windows-specific behaviour you should
know about when using Python on Microsoft Windows.

3.1. Installing Python¶

Unlike most Unix systems and services, Windows does not include a system
supported installation of Python. To make Python available, the CPython team
has compiled Windows installers (MSI packages) with every release for many years. These installers
are primarily intended to add a per-user installation of Python, with the
core interpreter and library being used by a single user. The installer is also
able to install for all users of a single machine, and a separate ZIP file is
available for application-local distributions.

3.1.1. Supported Versions¶

As specified in PEP 11, a Python release only supports a Windows platform
while Microsoft considers the platform under extended support. This means that
Python 3.6 supports Windows Vista and newer. If you require Windows XP
support then please install Python 3.4.

3.1.2. Installation Steps¶

Four Python 3.6 installers are available for download — two each for the
32-bit and 64-bit versions of the interpreter. The web installer is a small
initial download, and it will automatically download the required components as
necessary. The offline installer includes the components necessary for a
default installation and only requires an internet connection for optional
features. See Installing Without Downloading for other ways to avoid downloading
during installation.

After starting the installer, one of two options may be selected:

../_images/win_installer.png

If you select “Install Now”:

  • You will not need to be an administrator (unless a system update for the
    C Runtime Library is required or you install the Python Launcher for Windows for all
    users)
  • Python will be installed into your user directory
  • The Python Launcher for Windows will be installed according to the option at the bottom
    of the first page
  • The standard library, test suite, launcher and pip will be installed
  • If selected, the install directory will be added to your PATH
  • Shortcuts will only be visible for the current user

Selecting “Customize installation” will allow you to select the features to
install, the installation location and other options or post-install actions.
To install debugging symbols or binaries, you will need to use this option.

To perform an all-users installation, you should select “Customize
installation”. In this case:

  • You may be required to provide administrative credentials or approval
  • Python will be installed into the Program Files directory
  • The Python Launcher for Windows will be installed into the Windows directory
  • Optional features may be selected during installation
  • The standard library can be pre-compiled to bytecode
  • If selected, the install directory will be added to the system PATH
  • Shortcuts are available for all users

3.1.3. Removing the MAX_PATH Limitation¶

Windows historically has limited path lengths to 260 characters. This meant that
paths longer than this would not resolve and errors would result.

In the latest versions of Windows, this limitation can be expanded to
approximately 32,000 characters. Your administrator will need to activate the
“Enable Win32 long paths” group policy, or set the registry value
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlFileSystem@LongPathsEnabled
to 1.

This allows the open() function, the os module and most other
path functionality to accept and return paths longer than 260 characters when
using strings. (Use of bytes as paths is deprecated on Windows, and this feature
is not available when using bytes.)

After changing the above option, no further configuration is required.

Changed in version 3.6: Support for long paths was enabled in Python.

3.1.4. Installing Without UI¶

All of the options available in the installer UI can also be specified from the
command line, allowing scripted installers to replicate an installation on many
machines without user interaction. These options may also be set without
suppressing the UI in order to change some of the defaults.

To completely hide the installer UI and install Python silently, pass the
/quiet option. To skip past the user interaction but still display
progress and errors, pass the /passive option. The /uninstall
option may be passed to immediately begin removing Python — no prompt will be
displayed.

All other options are passed as name=value, where the value is usually
0 to disable a feature, 1 to enable a feature, or a path. The full list
of available options is shown below.

Name Description Default
InstallAllUsers Perform a system-wide installation. 0
TargetDir The installation directory Selected based on
InstallAllUsers
DefaultAllUsersTargetDir The default installation directory
for all-user installs
%ProgramFiles%Python X.Y or %ProgramFiles(x86)%Python X.Y
DefaultJustForMeTargetDir The default install directory for
just-for-me installs
%LocalAppData%ProgramsPythonXY or
%LocalAppData%ProgramsPythonXY-32
DefaultCustomTargetDir The default custom install directory
displayed in the UI
(empty)
AssociateFiles Create file associations if the
launcher is also installed.
1
CompileAll Compile all .py files to
.pyc.
0
PrependPath Add install and Scripts directories
tho PATH and .PY to
PATHEXT
0
Shortcuts Create shortcuts for the interpreter,
documentation and IDLE if installed.
1
Include_doc Install Python manual 1
Include_debug Install debug binaries 0
Include_dev Install developer headers and
libraries
1
Include_exe Install python.exe and
related files
1
Include_launcher Install Python Launcher for Windows. 1

Include_tools Install utility scripts 1
LauncherOnly Only installs the launcher. This
will override most other options.
0
SimpleInstall Disable most install UI 0
SimpleInstallDescription A custom message to display when the
simplified install UI is used.
(empty)

For example, to silently install a default, system-wide Python installation,
you could use the following command (from an elevated command prompt):

python-3.6.0.exe /quiet InstallAllUsers=1 PrependPath=1 Include_test=0

To allow users to easily install a personal copy of Python without the test
suite, you could provide a shortcut with the following command. This will
display a simplified initial page and disallow customization:

python-3.6.0.exe InstallAllUsers=0 Include_launcher=0 Include_test=0
    SimpleInstall=1 SimpleInstallDescription="Just for me, no test suite."

(Note that omitting the launcher also omits file associations, and is only
recommended for per-user installs when there is also a system-wide installation
that included the launcher.)

The options listed above can also be provided in a file named unattend.xml
alongside the executable. This file specifies a list of options and values.
When a value is provided as an attribute, it will be converted to a number if
possible. Values provided as element text are always left as strings. This
example file sets the same options and the previous example:

<Options>
    <Option Name="InstallAllUsers" Value="no" />
    <Option Name="Include_launcher" Value="0" />
    <Option Name="Include_test" Value="no" />
    <Option Name="SimpleInstall" Value="yes" />
    <Option Name="SimpleInstallDescription">Just for me, no test suite</Option>
</Options>

3.1.5. Installing Without Downloading¶

As some features of Python are not included in the initial installer download,
selecting those features may require an internet connection. To avoid this
need, all possible components may be downloaded on-demand to create a complete
layout that will no longer require an internet connection regardless of the
selected features. Note that this download may be bigger than required, but
where a large number of installations are going to be performed it is very
useful to have a locally cached copy.

Execute the following command from Command Prompt to download all possible
required files. Remember to substitute python-3.6.0.exe for the actual
name of your installer, and to create layouts in their own directories to
avoid collisions between files with the same name.

python-3.6.0.exe /layout [optional target directory]

You may also specify the /quiet option to hide the progress display.

3.1.6. Modifying an install¶

Once Python has been installed, you can add or remove features through the
Programs and Features tool that is part of Windows. Select the Python entry and
choose “Uninstall/Change” to open the installer in maintenance mode.

“Modify” allows you to add or remove features by modifying the checkboxes —
unchanged checkboxes will not install or remove anything. Some options cannot be
changed in this mode, such as the install directory; to modify these, you will
need to remove and then reinstall Python completely.

“Repair” will verify all the files that should be installed using the current
settings and replace any that have been removed or modified.

“Uninstall” will remove Python entirely, with the exception of the
Python Launcher for Windows, which has its own entry in Programs and Features.

3.1.7. Other Platforms¶

With ongoing development of Python, some platforms that used to be supported
earlier are no longer supported (due to the lack of users or developers).
Check PEP 11 for details on all unsupported platforms.

  • Windows CE is still supported.
  • The Cygwin installer offers to install the Python
    interpreter as well (cf. Cygwin package source, Maintainer releases)

See Python for Windows
for detailed information about platforms with pre-compiled installers.

3.2. Alternative bundles¶

Besides the standard CPython distribution, there are modified packages including
additional functionality. The following is a list of popular versions and their
key features:

ActivePython
Installer with multi-platform compatibility, documentation, PyWin32
Anaconda
Popular scientific modules (such as numpy, scipy and pandas) and the
conda package manager.
Canopy
A “comprehensive Python analysis environment” with editors and other
development tools.
WinPython
Windows-specific distribution with prebuilt scientific packages and
tools for building packages.

Note that these packages may not include the latest versions of Python or
other libraries, and are not maintained or supported by the core Python team.

3.3. Configuring Python¶

To run Python conveniently from a command prompt, you might consider changing
some default environment variables in Windows. While the installer provides an
option to configure the PATH and PATHEXT variables for you, this is only
reliable for a single, system-wide installation. If you regularly use multiple
versions of Python, consider using the Python Launcher for Windows.

3.3.1. Excursus: Setting environment variables¶

Windows allows environment variables to be configured permanently at both the
User level and the System level, or temporarily in a command prompt.

To temporarily set environment variables, open Command Prompt and use the
set command:

C:>set PATH=C:Program FilesPython 3.6;%PATH%
C:>set PYTHONPATH=%PYTHONPATH%;C:My_python_lib
C:>python

These changes will apply to any further commands executed in that console, and
will be inherited by any applications started from the console.

Including the variable name within percent signs will expand to the existing
value, allowing you to add your new value at either the start or the end.
Modifying PATH by adding the directory containing
python.exe to the start is a common way to ensure the correct version
of Python is launched.

To permanently modify the default environment variables, click Start and search
for ‘edit environment variables’, or open System properties, Advanced
system settings
and click the Environment Variables button.
In this dialog, you can add or modify User and System variables. To change
System variables, you need non-restricted access to your machine
(i.e. Administrator rights).

Note

Windows will concatenate User variables after System variables, which may
cause unexpected results when modifying PATH.

The PYTHONPATH variable is used by all versions of Python 2 and
Python 3, so you should not permanently configure this variable unless it
only includes code that is compatible with all of your installed Python
versions.

3.3.2. Finding the Python executable¶

Changed in version 3.5.

Besides using the automatically created start menu entry for the Python
interpreter, you might want to start Python in the command prompt. The
installer has an option to set that up for you.

On the first page of the installer, an option labelled “Add Python to PATH”
may be selected to have the installer add the install location into the
PATH. The location of the Scripts folder is also added.
This allows you to type python to run the interpreter, and
pip for the package installer. Thus, you can also execute your
scripts with command line options, see Command line documentation.

If you don’t enable this option at install time, you can always re-run the
installer, select Modify, and enable it. Alternatively, you can manually
modify the PATH using the directions in Excursus: Setting environment variables. You
need to set your PATH environment variable to include the directory
of your Python installation, delimited by a semicolon from other entries. An
example variable could look like this (assuming the first two entries already
existed):

C:WINDOWSsystem32;C:WINDOWS;C:Program FilesPython 3.6

3.4. Python Launcher for Windows¶

New in version 3.3.

The Python launcher for Windows is a utility which aids in locating and
executing of different Python versions. It allows scripts (or the
command-line) to indicate a preference for a specific Python version, and
will locate and execute that version.

Unlike the PATH variable, the launcher will correctly select the most
appropriate version of Python. It will prefer per-user installations over
system-wide ones, and orders by language version rather than using the most
recently installed version.

3.4.1. Getting started¶

3.4.1.1. From the command-line¶

Changed in version 3.6.

System-wide installations of Python 3.3 and later will put the launcher on your
PATH. The launcher is compatible with all available versions of
Python, so it does not matter which version is installed. To check that the
launcher is available, execute the following command in Command Prompt:

You should find that the latest version of Python you have installed is
started — it can be exited as normal, and any additional command-line
arguments specified will be sent directly to Python.

If you have multiple versions of Python installed (e.g., 2.7 and 3.6) you
will have noticed that Python 3.6 was started — to launch Python 2.7, try
the command:

If you want the latest version of Python 2.x you have installed, try the
command:

You should find the latest version of Python 2.x starts.

If you see the following error, you do not have the launcher installed:

'py' is not recognized as an internal or external command,
operable program or batch file.

Per-user installations of Python do not add the launcher to PATH
unless the option was selected on installation.

3.4.1.2. Virtual environments¶

New in version 3.5.

If the launcher is run with no explicit Python version specification, and a
virtual environment (created with the standard library venv module or
the external virtualenv tool) active, the launcher will run the virtual
environment’s interpreter rather than the global one. To run the global
interpreter, either deactivate the virtual environment, or explicitly specify
the global Python version.

3.4.1.3. From a script¶

Let’s create a test Python script — create a file called hello.py with the
following contents

#! python
import sys
sys.stdout.write("hello from Python %sn" % (sys.version,))

From the directory in which hello.py lives, execute the command:

You should notice the version number of your latest Python 2.x installation
is printed. Now try changing the first line to be:

Re-executing the command should now print the latest Python 3.x information.
As with the above command-line examples, you can specify a more explicit
version qualifier. Assuming you have Python 2.6 installed, try changing the
first line to #! python2.6 and you should find the 2.6 version
information printed.

Note that unlike interactive use, a bare “python” will use the latest
version of Python 2.x that you have installed. This is for backward
compatibility and for compatibility with Unix, where the command python
typically refers to Python 2.

3.4.1.4. From file associations¶

The launcher should have been associated with Python files (i.e. .py,
.pyw, .pyc files) when it was installed. This means that
when you double-click on one of these files from Windows explorer the launcher
will be used, and therefore you can use the same facilities described above to
have the script specify the version which should be used.

The key benefit of this is that a single launcher can support multiple Python
versions at the same time depending on the contents of the first line.

3.4.2. Shebang Lines¶

If the first line of a script file starts with #!, it is known as a
“shebang” line. Linux and other Unix like operating systems have native
support for such lines and they are commonly used on such systems to indicate
how a script should be executed. This launcher allows the same facilities to
be used with Python scripts on Windows and the examples above demonstrate their
use.

To allow shebang lines in Python scripts to be portable between Unix and
Windows, this launcher supports a number of ‘virtual’ commands to specify
which interpreter to use. The supported virtual commands are:

  • /usr/bin/env python
  • /usr/bin/python
  • /usr/local/bin/python
  • python

For example, if the first line of your script starts with

The default Python will be located and used. As many Python scripts written
to work on Unix will already have this line, you should find these scripts can
be used by the launcher without modification. If you are writing a new script
on Windows which you hope will be useful on Unix, you should use one of the
shebang lines starting with /usr.

Any of the above virtual commands can be suffixed with an explicit version
(either just the major version, or the major and minor version) — for example
/usr/bin/python2.7 — which will cause that specific version to be located
and used.

The /usr/bin/env form of shebang line has one further special property.
Before looking for installed Python interpreters, this form will search the
executable PATH for a Python executable. This corresponds to the
behaviour of the Unix env program, which performs a PATH search.

3.4.3. Arguments in shebang lines¶

The shebang lines can also specify additional options to be passed to the
Python interpreter. For example, if you have a shebang line:

Then Python will be started with the -v option

3.4.4. Customization¶

3.4.4.1. Customization via INI files¶

Two .ini files will be searched by the launcher — py.ini in the current
user’s “application data” directory (i.e. the directory returned by calling the
Windows function SHGetFolderPath with CSIDL_LOCAL_APPDATA) and py.ini in the
same directory as the launcher. The same .ini files are used for both the
‘console’ version of the launcher (i.e. py.exe) and for the ‘windows’ version
(i.e. pyw.exe)

Customization specified in the “application directory” will have precedence over
the one next to the executable, so a user, who may not have write access to the
.ini file next to the launcher, can override commands in that global .ini file)

3.4.4.2. Customizing default Python versions¶

In some cases, a version qualifier can be included in a command to dictate
which version of Python will be used by the command. A version qualifier
starts with a major version number and can optionally be followed by a period
(‘.’) and a minor version specifier. If the minor qualifier is specified, it
may optionally be followed by “-32” to indicate the 32-bit implementation of
that version be used.

For example, a shebang line of #!python has no version qualifier, while
#!python3 has a version qualifier which specifies only a major version.

If no version qualifiers are found in a command, the environment variable
PY_PYTHON can be set to specify the default version qualifier — the default
value is “2”. Note this value could specify just a major version (e.g. “2”) or
a major.minor qualifier (e.g. “2.6”), or even major.minor-32.

If no minor version qualifiers are found, the environment variable
PY_PYTHON{major} (where {major} is the current major version qualifier
as determined above) can be set to specify the full version. If no such option
is found, the launcher will enumerate the installed Python versions and use
the latest minor release found for the major version, which is likely,
although not guaranteed, to be the most recently installed version in that
family.

On 64-bit Windows with both 32-bit and 64-bit implementations of the same
(major.minor) Python version installed, the 64-bit version will always be
preferred. This will be true for both 32-bit and 64-bit implementations of the
launcher — a 32-bit launcher will prefer to execute a 64-bit Python installation
of the specified version if available. This is so the behavior of the launcher
can be predicted knowing only what versions are installed on the PC and
without regard to the order in which they were installed (i.e., without knowing
whether a 32 or 64-bit version of Python and corresponding launcher was
installed last). As noted above, an optional “-32” suffix can be used on a
version specifier to change this behaviour.

Examples:

  • If no relevant options are set, the commands python and
    python2 will use the latest Python 2.x version installed and
    the command python3 will use the latest Python 3.x installed.
  • The commands python3.1 and python2.7 will not consult any
    options at all as the versions are fully specified.
  • If PY_PYTHON=3, the commands python and python3 will both use
    the latest installed Python 3 version.
  • If PY_PYTHON=3.1-32, the command python will use the 32-bit
    implementation of 3.1 whereas the command python3 will use the latest
    installed Python (PY_PYTHON was not considered at all as a major
    version was specified.)
  • If PY_PYTHON=3 and PY_PYTHON3=3.1, the commands
    python and python3 will both use specifically 3.1

In addition to environment variables, the same settings can be configured
in the .INI file used by the launcher. The section in the INI file is
called [defaults] and the key name will be the same as the
environment variables without the leading PY_ prefix (and note that
the key names in the INI file are case insensitive.) The contents of
an environment variable will override things specified in the INI file.

For example:

  • Setting PY_PYTHON=3.1 is equivalent to the INI file containing:
  • Setting PY_PYTHON=3 and PY_PYTHON3=3.1 is equivalent to the INI file
    containing:
[defaults]
python=3
python3=3.1

3.4.5. Diagnostics¶

If an environment variable PYLAUNCH_DEBUG is set (to any value), the
launcher will print diagnostic information to stderr (i.e. to the console).
While this information manages to be simultaneously verbose and terse, it
should allow you to see what versions of Python were located, why a
particular version was chosen and the exact command-line used to execute the
target Python.

3.5. Finding modules¶

Python usually stores its library (and thereby your site-packages folder) in the
installation directory. So, if you had installed Python to
C:Python, the default library would reside in
C:PythonLib and third-party modules should be stored in
C:PythonLibsite-packages.

To completely override sys.path, create a ._pth file with the same
name as the DLL (python36._pth) or the executable (python._pth) and
specify one line for each path to add to sys.path. The file based on the
DLL name overrides the one based on the executable, which allows paths to be
restricted for any program loading the runtime if desired.

When the file exists, all registry and environment variables are ignored,
isolated mode is enabled, and site is not imported unless one line in the
file specifies import site. Blank paths and lines starting with # are
ignored. Each path may be absolute or relative to the location of the file.
Import statements other than to site are not permitted, and arbitrary code
cannot be specified.

Note that .pth files (without leading underscore) will be processed normally
by the site module.

When no ._pth file is found, this is how sys.path is populated on
Windows:

  • An empty entry is added at the start, which corresponds to the current
    directory.
  • If the environment variable PYTHONPATH exists, as described in
    Environment variables, its entries are added next. Note that on Windows,
    paths in this variable must be separated by semicolons, to distinguish them
    from the colon used in drive identifiers (C: etc.).
  • Additional “application paths” can be added in the registry as subkeys of
    SOFTWAREPythonPythonCoreversionPythonPath under both the
    HKEY_CURRENT_USER and HKEY_LOCAL_MACHINE hives. Subkeys which have
    semicolon-delimited path strings as their default value will cause each path
    to be added to sys.path. (Note that all known installers only use
    HKLM, so HKCU is typically empty.)
  • If the environment variable PYTHONHOME is set, it is assumed as
    “Python Home”. Otherwise, the path of the main Python executable is used to
    locate a “landmark file” (either Libos.py or pythonXY.zip) to deduce
    the “Python Home”. If a Python home is found, the relevant sub-directories
    added to sys.path (Lib, plat-win, etc) are based on that
    folder. Otherwise, the core Python path is constructed from the PythonPath
    stored in the registry.
  • If the Python Home cannot be located, no PYTHONPATH is specified in
    the environment, and no registry entries can be found, a default path with
    relative entries is used (e.g. .Lib;.plat-win, etc).

If a pyvenv.cfg file is found alongside the main executable or in the
directory one level above the executable, the following variations apply:

  • If home is an absolute path and PYTHONHOME is not set, this
    path is used instead of the path to the main executable when deducing the
    home location.

The end result of all this is:

  • When running python.exe, or any other .exe in the main Python
    directory (either an installed version, or directly from the PCbuild
    directory), the core path is deduced, and the core paths in the registry are
    ignored. Other “application paths” in the registry are always read.
  • When Python is hosted in another .exe (different directory, embedded via COM,
    etc), the “Python Home” will not be deduced, so the core path from the
    registry is used. Other “application paths” in the registry are always read.
  • If Python can’t find its home and there are no registry value (frozen .exe,
    some very strange installation setup) you get a path with some default, but
    relative, paths.

For those who want to bundle Python into their application or distribution, the
following advice will prevent conflicts with other installations:

  • Include a ._pth file alongside your executable containing the
    directories to include. This will ignore paths listed in the registry and
    environment variables, and also ignore site unless import site is
    listed.
  • If you are loading python3.dll or python36.dll in your own
    executable, explicitly call Py_SetPath() or (at least)
    Py_SetProgramName() before Py_Initialize().
  • Clear and/or overwrite PYTHONPATH and set PYTHONHOME
    before launching python.exe from your application.
  • If you cannot use the previous suggestions (for example, you are a
    distribution that allows people to run python.exe directly), ensure
    that the landmark file (Libos.py) exists in your install directory.
    (Note that it will not be detected inside a ZIP file, but a correctly named
    ZIP file will be detected instead.)

These will ensure that the files in a system-wide installation will not take
precedence over the copy of the standard library bundled with your application.
Otherwise, your users may experience problems using your application. Note that
the first suggestion is the best, as the other may still be susceptible to
non-standard paths in the registry and user site-packages.

Changed in version 3.6:

  • Adds ._pth file support and removes applocal option from
    pyvenv.cfg.
  • Adds pythonXX.zip as a potential landmark when directly adjacent
    to the executable.

Deprecated since version 3.6:

Modules specified in the registry under Modules (not PythonPath)
may be imported by importlib.machinery.WindowsRegistryFinder.
This finder is enabled on Windows in 3.6.0 and earlier, but may need to
be explicitly added to sys.meta_path in the future.

3.6. Additional modules¶

Even though Python aims to be portable among all platforms, there are features
that are unique to Windows. A couple of modules, both in the standard library
and external, and snippets exist to use these features.

The Windows-specific standard modules are documented in
MS Windows Specific Services.

3.6.1. PyWin32¶

The PyWin32 module by Mark Hammond
is a collection of modules for advanced Windows-specific support. This includes
utilities for:

  • Component Object Model (COM)
  • Win32 API calls
  • Registry
  • Event log
  • Microsoft Foundation Classes (MFC)
    user interfaces

PythonWin is a sample MFC application
shipped with PyWin32. It is an embeddable IDE with a built-in debugger.

3.6.2. cx_Freeze¶

cx_Freeze is a distutils
extension (see Extending Distutils) which wraps Python scripts into
executable Windows programs (*.exe files). When you have done this,
you can distribute your application without requiring your users to install
Python.

3.6.3. WConio¶

Since Python’s advanced terminal handling layer, curses, is restricted to
Unix-like systems, there is a library exclusive to Windows as well: Windows
Console I/O for Python.

WConio is a wrapper for
Turbo-C’s CONIO.H, used to create text user interfaces.

3.7. Compiling Python on Windows¶

If you want to compile CPython yourself, first thing you should do is get the
source. You can download either the
latest release’s source or just grab a fresh checkout.

The source tree contains a build solution and project files for Microsoft
Visual Studio 2015, which is the compiler used to build the official Python
releases. These files are in the PCbuild directory.

Check PCbuild/readme.txt for general information on the build process.

For extension modules, consult Building C and C++ Extensions on Windows.

3.8. Embedded Distribution¶

New in version 3.5.

The embedded distribution is a ZIP file containing a minimal Python environment.
It is intended for acting as part of another application, rather than being
directly accessed by end-users.

When extracted, the embedded distribution is (almost) fully isolated from the
user’s system, including environment variables, system registry settings, and
installed packages. The standard library is included as pre-compiled and
optimized .pyc files in a ZIP, and python3.dll, python36.dll,
python.exe and pythonw.exe are all provided. Tcl/tk (including all
dependants, such as Idle), pip and the Python documentation are not included.

Note

The embedded distribution does not include the Microsoft C Runtime and it is
the responsibility of the application installer to provide this. The
runtime may have already been installed on a user’s system previously or
automatically via Windows Update, and can be detected by finding
ucrtbase.dll in the system directory.

Third-party packages should be installed by the application installer alongside
the embedded distribution. Using pip to manage dependencies as for a regular
Python installation is not supported with this distribution, though with some
care it may be possible to include and use pip for automatic updates. In
general, third-party packages should be treated as part of the application
(“vendoring”) so that the developer can ensure compatibility with newer
versions before providing updates to users.

The two recommended use cases for this distribution are described below.

3.8.1. Python Application¶

An application written in Python does not necessarily require users to be aware
of that fact. The embedded distribution may be used in this case to include a
private version of Python in an install package. Depending on how transparent it
should be (or conversely, how professional it should appear), there are two
options.

Using a specialized executable as a launcher requires some coding, but provides
the most transparent experience for users. With a customized launcher, there are
no obvious indications that the program is running on Python: icons can be
customized, company and version information can be specified, and file
associations behave properly. In most cases, a custom launcher should simply be
able to call Py_Main with a hard-coded command line.

The simpler approach is to provide a batch file or generated shortcut that
directly calls the python.exe or pythonw.exe with the required
command-line arguments. In this case, the application will appear to be Python
and not its actual name, and users may have trouble distinguishing it from other
running Python processes or file associations.

With the latter approach, packages should be installed as directories alongside
the Python executable to ensure they are available on the path. With the
specialized launcher, packages can be located in other locations as there is an
opportunity to specify the search path before launching the application.

3.8.2. Embedding Python¶

Applications written in native code often require some form of scripting
language, and the embedded Python distribution can be used for this purpose. In
general, the majority of the application is in native code, and some part will
either invoke python.exe or directly use python3.dll. For either case,
extracting the embedded distribution to a subdirectory of the application
installation is sufficient to provide a loadable Python interpreter.

As with the application use, packages can be installed to any location as there
is an opportunity to specify search paths before initializing the interpreter.
Otherwise, there is no fundamental differences between using the embedded
distribution and a regular installation.

Python — интерпретируемый, динамический, объектно-ориентированный язык программирования. Включает в себя модули, исключения, динамическую типизацию, классы и высокоуровневые типы данных. Поддерживает множество парадигм программирования, помимо объектно-ориентированного программирования, таких как процедурное и функциональное программирование.

Python сочетает в себе удивительную мощь с очень понятным синтаксисом. Его также можно использовать как язык расширения для приложений, которым нужен программируемый интерфейс. Кроме этого, Python мультиплатформенный: он работает на Windows, а также на различных Unix-системах, включая Linux и macOS.

Ключевые особенности Python:

  • для выделения фрагментов кода используются отступы, что улучшает читаемость и чистоту кода;
  • стандартный дистрибутив имеет большое количество полезных модулей;
  • возможность использования Python в диалоговом режиме;
  • стандартный дистрибутив имеет достаточно мощную среду разработки (IDLE), написанную на Python;
  • имеет инструменты для работы с комплексными числами, может оперировать с целыми числами произвольной величины, в диалоговом режиме может использоваться как мощный калькулятор);
  • открытый код.
