Configure Python. Using Python on a Mac. This document aims to give an overview of Windows-specific behaviour you should know about when using Python on Microsoft Windows. Unlike most Unix systems and services, Windows does not include a system supported installation of Python. 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. 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. If you require Windows 7 support, please install Python 3.

There are a number of different installers available for Windows, each with certain benefits and downsides. The full installer contains all components and is the best option for developers using Python for any kind of project.

The Microsoft Store package is a simple installation of Python that is suitable for running scripts and packages, and using IDLE or other development environments. It requires Windows 10 and above, but can be safely installed without corrupting other programs.

It also provides many convenient commands for launching Python and its tools. The nuget. It can be used to build Python packages or run scripts, but is not updateable and has no user interface tools. The embeddable package is a minimal package of Python suitable for embedding into a larger application. Four Python 3. 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. 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. The Python Launcher for Windows will be installed according to the option at the bottom of the first page.

If selected, the install directory will be added to your PATH. To install debugging symbols or binaries, you will need to use this option. The Python Launcher for Windows will be installed into the Windows directory. If selected, the install directory will be added to the system PATH. Windows historically has limited path lengths to 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, characters.

This allows the open function, the os module and most other path functionality to accept and return paths longer than characters. Changed in version 3. 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. The full list of available options is shown below. Compile all. Install python. Omitting this may lead to an unusable installation.

Install Python Launcher for Windows. Installs the launcher for all users. Install standard library and extension modules. For example, to silently install a default, system-wide Python installation, you could use the following command from an elevated command prompt :.

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:. 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. 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 as the previous example:. 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 Once Python has been installed, you can add or remove features through the Programs and Features tool that is part of Windows. 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. The Microsoft Store package is an easily installable Python interpreter that is intended mainly for interactive use, for example, by students.

Ensure that the app you select is published by the Python Software Foundation, and install it. Python will always be available for free on the Microsoft Store.

If you are asked to pay for it, you have not selected the correct package. After installation, Python may be launched by finding it in Start. Alternatively, it will be available from any Command Prompt or PowerShell session by typing python.

Further, pip and IDLE may be used by typing pip or idle. IDLE can also be found in Start. All three commands are also available with version number suffixes, for example, as python3. It is recommended to make sure that pip and idle are consistent with whichever version of python is selected. Virtual environments can be created with python -m venv and activated and used as normal.

If you have installed another version of Python and added it to your PATH variable, it will be available as python. To access the new installation, use python3. The py. Uninstalling will remove all packages you installed directly into this Python installation, but will not remove any virtual environments.

Because of restrictions on Microsoft Store apps, Python scripts may not have full write access to shared locations such as TEMP and the registry. Instead, it will write to a private copy.

If your scripts must modify the shared locations, you will need to install the full installer. At runtime, Python will use a private copy of well-known Windows folders and the registry. When reading files, Windows will return the file from the private folder, or if that does not exist, the real Windows directory. You can find the real path of any existing file using os. Visit nuget. What follows is a summary that is sufficient for Python developers.

With the tool, the latest version of Python for bit or bit machines is installed using:. To select a particular version, add a -Version 3. The output directory may be changed from. By default, the subdirectory is named the same as the package, and without the -ExcludeVersion option this name will include the specific version installed.

Inside the subdirectory is a tools directory that contains the Python installation:. In general, nuget packages are not upgradeable, and newer versions should be installed side-by-side and referenced using the full path.

Alternatively, delete the package directory manually and install it again. Many CI systems will do this automatically if they do not preserve files between builds. This contains a MSBuild properties file python. Including the settings will automatically use the headers and import libraries in your build.

The package information pages on nuget. 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. The standard library is included as pre-compiled and optimized. The embedded distribution does not include the Microsoft C Runtime and it is the responsibility of the application installer to provide this.

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.

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.
