pip is a de facto standard package-management system used to install and manage software packages written in Python.[4] Many packages can be found in the default source for packages and their dependencies — Python Package Index (PyPI).[5]
Most distributions of Python come with pip preinstalled. Python 2.7.9 and later (on the python2 series), and Python 3.4 and later include pip (pip3 for Python 3) by default.[6]
pip is a recursive acronym for "Pip Installs Packages".[7]
Command-line interface
pip install virtualenvOne major advantage of pip is the ease of its command-line interface, which makes installing Python software packages as easy as issuing a command:
pip install some-package-name
Users can also easily remove the package:
pip uninstall some-package-name
Most importantly pip has a feature to manage full lists of packages and corresponding version numbers, possible through a "requirements" file.[5] This permits the efficient re-creation of an entire group of packages in a separate environment (e.g. another computer) or virtual environment. This can be achieved with a properly formatted file and the following command[8], where requirements.txt is the name of the file:
pip install -r requirements.txt
Install some package for a specific version python, where ${version} is replaced for 2, 3, 3.4, etc.:
pip${version} install some-package-name
