Questions tagged [pylance]

Pylance is an extension for Visual Studio Code that provides a language server for Python. When applying this tag to your question, consider also tagging it with [visual-studio-code] and/or [python].

Pylance is a language server to support the core Python extension for Visual Studio Code. Its aim is to help developers write Python code better and faster by providing auto-imports, semantic highlighting, built-in reporting of warnings and errors, strict type-checking, and method signatures with type information when displaying the popup Intellisense documentation.

It was first introduced in a post on Microsoft's Python development blog: Announcing Pylance: Fast, feature-rich language support for Python in Visual Studio Code:

To deliver an improved user experience, we’ve created Pylance as a brand-new language server based on Microsoft’s Pyright static type checking tool. Pylance leverages type stubs (.pyi files) and lazy type inferencing to provide a highly-performant development experience. Pylance supercharges your Python IntelliSense experience with rich type information, helping you write better code, faster. The Pylance extension is also shipped with a collection of type stubs for popular modules to provide fast and accurate auto-completions and type checking.

It was made available starting VS Code 1.49 (2020.8.0 (12 August 2020) release).

  1. Expose Pylance setting in python.languageServer. If Pylance extension is not installed, prompt user to install it. (#13122)

Installation is straightforward:

  1. Install the Pylance extension
  2. Configure your settings.json file 
    "python.languageServer": "Pylance",
  3. Open a .py file and the extension should activate
