What is PyPI (Python Package Index)?

PyPI is the Python Package Index, a “repository of software for the Python programming language.”

PyPI provides a means for package developers to share Python packages with the community and for programmers to discover and install these Python packages.

PyPI is maintained by the Python Packaging Authority (PyPA).

PEP 503 defines the PyPI API whereby developers can define their own package indices accessible via pip and other installers. For example, many companys host their own private package index for internal use.
