Company Overview
pip is the official standard package installer for the Python ecosystem, created by Ian Bicking in 2008. The name "pip" is a recursive acronym for "Pip Installs Packages". Maintained by the Python Packaging Authority (PyPA), pip is the most widely used dependency management tool in the Python community.
Since Python 3.4, pip has been bundled with Python's standard distribution, making it available by default with every Python installation. It installs and manages third-party packages from the Python Package Index (PyPI), serving as essential infrastructure for Python development.
