Windows 10 Pro – Python, Path variables, and the Windows Store – Microsoft Community

 

For beginners who are new to Python, we recommend you install Python from the Microsoft Store. Installing via the Microsoft Store uses the basic Python3 interpreter, but handles set up of your PATH settings for the current user avoiding the need for admin access , in addition to providing automatic updates. This is especially helpful if you are in an educational environment or a part of an organization that restricts permissions or administrative access on your machine. If you are using Python on Windows for web development , we recommend a different set up for your development environment.

Rather than installing directly on Windows, we recommend installing and using Python via the Windows Subsystem for Linux. For help, see: Get started using Python for web development on Windows. If you’re interested in automating common tasks on your operating system, see our guide: Get started using Python on Windows for scripting and automation. We only recommend this if you are a more advanced Python programmer with a specific reason for choosing an alternative implementation.

Go to your Start menu lower left Windows icon , type “Microsoft Store”, select the link to open the store. Once the store is open, select Search from the upper-right menu and enter “Python”.

Select which version of Python you would like to use from the results under Apps. We recommend using the most recent unless you have a reason not to such as aligning with the version used on a pre-existing project that you plan to work on.

Once you’ve determined which version you would like to install, select Get. Once Python has completed the downloading and installation process, open Windows PowerShell using the Start menu lower left Windows icon.

Once PowerShell is open, enter Python –version to confirm that Python3 has installed on your machine. The Microsoft Store installation of Python includes pip , the standard package manager. Pip allows you to install and manage additional packages that are not part of the Python standard library.

To confirm that you also have pip available to install and manage packages, enter pip –version. VS Code also contains a built-in terminal that enables you to open a Python command line with Windows Command prompt, PowerShell, or whatever you prefer, establishing a seamless workflow between your code editor and command line. Once VS Code has been installed, you must also install the Python extension.

Python is an interpreted language, and in order to run Python code, you must tell VS Code which interpreter to use.

We recommend using the most recent version of Python unless you have a specific reason for choosing something different. You can also use the Select Python Environment option on the bottom Status Bar if available it may already show a selected interpreter.

The command presents a list of available interpreters that VS Code can find automatically, including virtual environments. If you don’t see the desired interpreter, see Configuring Python environments. The default terminal is PowerShell. Try the Python interpreter out by entering: print “Hello World”.

Python will return your statement “Hello World”. 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.

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.

The simpler approach is to provide a batch file or generated shortcut that directly calls the python. 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. 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. 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.

Besides the standard CPython distribution, there are modified packages including additional functionality. The following is a list of popular versions and their key features:. Popular scientific modules such as numpy, scipy and pandas and the conda package manager.

Previously Enthought provided Canopy, but it reached end of life in 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.

To run Python conveniently from a command prompt, you might consider changing some default environment variables in Windows. If you regularly use multiple versions of Python, consider using the Python Launcher for Windows.

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:. Oftentimes, this needs to be done when installing Python. In the System variables section, selecting the Path variable and clicking on Edit. The next screen will show all the directories that are currently a part of the PATH variable.

Python can now be used directly from the command prompt without having to write its location. Try executing the command python –version ; it will output the version of Python installed on your system. For Enterprise. For Individuals. For Bootcamps. Educative Learning. Educative Onboarding.
