# Python extension for Visual Studio Code

A [Visual Studio Code](https://code.visualstudio.com/) [extension](https://marketplace.visualstudio.com/VSCode) with rich support for the [Python language](https://www.python.org/) (for all [actively supported Python versions](https://devguide.python.org/versions/#supported-versions)), providing access points for extensions to seamlessly integrate and offer support for IntelliSense (Pylance), debugging (Python Debugger), formatting, linting, code navigation, refactoring, variable explorer, test explorer, and more!

## Support for [vscode.dev](https://vscode.dev/)

The Python extension does offer [some support](https://github.com/microsoft/vscode-python/wiki/Partial-mode) when running on [vscode.dev](https://vscode.dev/) (which includes [github.dev](http://github.dev/)). This includes partial IntelliSense for open files in the editor.


## Installed extensions

The Python extension will automatically install the following extensions by default to provide the best Python development experience in VS Code:

- [Pylance](https://marketplace.visualstudio.com/items?itemName=ms-python.vscode-pylance) - to provide performant Python language support
- [Python Debugger](https://marketplace.visualstudio.com/items?itemName=ms-python.debugpy) - to provide a seamless debug experience with debugpy

These extensions are optional dependencies, meaning the Python extension will remain fully functional if they fail to be installed. Any or all of these extensions can be [disabled](https://code.visualstudio.com/docs/editor/extension-marketplace#_disable-an-extension) or [uninstalled](https://code.visualstudio.com/docs/editor/extension-marketplace#_uninstall-an-extension) at the expense of some features. Extensions installed through the marketplace are subject to the [Marketplace Terms of Use](https://cdn.vsassets.io/v/M146_20190123.39/_content/Microsoft-Visual-Studio-Marketplace-Terms-of-Use.pdf).

## Extensibility 

The Python extension provides pluggable access points for extensions that extend various feature areas to further improve your Python development experience. These extensions are all optional and depend on your project configuration and preferences. 

- [Python formatters](https://code.visualstudio.com/docs/python/formatting#_choose-a-formatter)
- [Python linters](https://code.visualstudio.com/docs/python/linting#_choose-a-linter)

If you encounter issues with any of the listed extensions, please file an issue in its corresponding repo.
