Pylance is Microsoft's fast, feature-rich Python language server extension for Visual Studio Code, providing IntelliSense, auto-imports, diagnostics, and type checking. This repository hosts its documentation and issue tracker; the core typing engine is the open-source Pyright project, while Pylance itself is proprietary.

Use cases

• get better python autocomplete in vscode
• fix python import suggestions in vs code
• type check python code as i type
• speed up python language server in large projects
• enable semantic highlighting for python
• use python intellisense in jupyter notebooks
• install type stubs for my python dependencies

When to choose

• you use Visual Studio Code for Python development and want the default, best-integrated language server
• you need fast completions, auto-imports, and as-you-type diagnostics for Python 3
• you want optional static type checking powered by the Pyright engine
• you work with Jupyter notebooks or multi-root workspaces in VS Code

When to avoid

• you need a fully open-source language server - use Pyright or python-lsp-server instead
• you use an editor other than VS Code that cannot run VS Code extensions
• you require modifying the language server's source code, since Pylance is closed-source
