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).[2]
Python 2.7.9 and later (on the python2 series), and Python 3.4 and later include pip by default.[3]
pip is a recursive acronym that can stand for either "Pip Installs Packages" or "Pip Installs Python".[4][5]
Command-line interface
One major advantage of pip is the ease of its command-line interface, which makes installing Python software packages as easy as issuing one command:
pip install some-package-name
Users can also easily implement the package's subsequent removal:
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.[2] 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 requirements.txt file and the following command:
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
Web hosting service use
Pip is used to support the use of Python in cloud web hosting, such as by Heroku.[6]
