If you plan to collaborate with others on your Python code, or host your project on an open-source site like GitHub , VS Code supports version control with Git. You first need to install Git to power the Source Control panel. Download and install Git for Windows from the git-scm website. An Install Wizard is included that will ask you a series of questions about settings for your Git installation. We recommend using all of the default settings, unless you have a specific reason for changing something.
If you\’ve never worked with Git before, GitHub Guides can help you get started. Python is an interpreted language. In contrast to compiled languages, in which the code you write needs to be translated into machine code in order to be run by your computer\’s processor, Python code is passed straight to an interpreter and run directly.
You just type in your code and run it. Let\’s try it! With your PowerShell command line open, enter python to run the Python 3 interpreter. Some instructions prefer to use the command py or python3 , these should also work. There are several built-in methods that allow you to make modifications to strings in Python. Press Enter for a new line. Print your variable with: print variable.
This will display the text \”Hello World! Find out the length, how many characters are used, of your string variable with: len variable. This will display that there are 12 characters used. Note that the blank space it counted as a character in the total length. Convert your string variable to upper-case letters: variable. Now convert your string variable to lower-case letters: variable. For most Unix systems, you must download and compile the source code. The same source code archive can also be used to build the Windows and Mac versions, and is the starting point for ports to all other platforms.
Download the latest Python 3 and Python 2 source. This site hosts the \”traditional\” implementation of Python nicknamed CPython. A number of alternative implementations are available as well. Source and binary executables are signed by the release manager or binary builder using their OpenPGP key. Release files for currently supported releases are signed by the following:. Release files for older releases which have now reached end-of-life may have been signed by one of the following:.
You can import a person\’s public keys from a public keyserver network server you trust by running a command like:. On the version-specific download pages, you should see a link to both the downloadable file and a detached signature file.
Once you have Python installed, install pygame from the command line or the terminal from within VS Code by typing python -m pip install -U pygame –user. Navigate to this folder and create a file named \”bounce. Open the folder in VS Code:. Read more about writing games with pygame at pygame. We recommend the following resources to support you in continuing to learn about Python development on Windows. Introduction to Python : Try the interactive Microsoft Learn platform and earn experience points for completing this module covering the basics on how to write basic Python code, declare variables, and work with console input and output.
The interactive sandbox environment makes this a great place to start for folks who don\’t have their Python development environment set up yet. Python on Pluralsight: 8 Courses, 29 Hours : The Python learning path on Pluralsight offers online courses covering a variety of topics related to Python, including a tool to measure your skill and find your gaps.
The Python. Learning Python on Lynda. Linting Python : Linting is the process of running a program that will analyse code for potential errors. Learn about the different forms of linting support VS Code provides for Python and how to set it up. Debugging Python : Debugging is the process of identifying and removing errors from a computer program.
This article covers how to initialize and configure debugging for Python with VS Code, how to set and validate breakpoints, attach a local script, perform debugging for different app types or on a remote computer, and some basic troubleshooting. Unit testing Python : Covers some background explaining what unit testing means, an example walkthrough, enabling a test framework, creating and running your tests, debugging tests, and test configuration settings.

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.
