The Python Package Index (PyPI) is the official third-party public software repository for the Python programming language. PyPI helps users find, install, and distribute software developed and shared by the Python community. Pip, the Python package installation tool, is used to install files from PyPI.

PyPI is maintained by an independent group of developers known as the Python Packaging Authority (PyPA), and is supported by the Python Packaging Working Group (PackagingWG).
