pip is a package management system used to install and manage software packages written in Python. Many packages can be found in the Python Package Index (PyPI).

Python 2.7.9 and later (on the python2 series), and Python 3.4 and later include pip (pip3 for Python 3) by default.

pip is a recursive acronym that can stand for either “Pip Installs Packages” or “Pip installs Python”.
