The Python package installer
Pip is the package installer for Python, enabling users to install packages from the Python Package Index and other indexes. The project is written in Python and uses a vendoring approach to bundle dependencies like setuptools, packaging, requests, and platformdirs directly into pip's codebase to ensure stability and security. The material indicates pip is maintained by the Python Packaging Authority (PyPA) and releases updates every three months, with development coordinated through GitHub, mailing lists, and IRC channels.
