Pylance
Pylance is a language server and static type checker for Python, developed by Microsoft and integrated into Visual Studio Code. It provides intelligent code completion, type checking, and code navigation features by leveraging static type information and the Language Server Protocol (LSP). It enhances the development experience by offering real-time feedback and analysis for Python code.
Developers should use Pylance when working on Python projects in Visual Studio Code to improve code quality and productivity, especially in large or complex codebases. It is particularly valuable for projects using type hints (PEP 484) as it provides accurate type checking and autocompletion, reducing runtime errors and speeding up development. It's also useful for refactoring and understanding code dependencies through its navigation features.
