An implementation of the Language Server Protocol (LSP) for Python, built on Jedi for completions, definitions, hover, references, and symbols. It supports optional linters and formatters (pycodestyle, pyflakes, autopep8, YAPF) and third-party plugins like pyls-mypy and pyls-black.

Use cases

• add python autocomplete to my editor via lsp
• language server for python in vim or emacs
• get go-to-definition and references for python code
• run pycodestyle and pyflakes diagnostics inside my editor
• format python code with yapf or autopep8 through lsp
• extend a python language server with custom plugins

When to choose

• you need an LSP server for Python 2.7 or older Python 3.5+ environments
• you want a plugin-based language server with optional linters and formatters
• your editor client supports pyls configuration sources like pycodestyle or flake8

When to avoid

• you want the actively developed successor python-lsp-server (pylsp) instead of this fork
• you need Python 3.8+ only features or modern tooling integration
• you prefer a non-LSP static analysis tool
