pip is a package-management system used to install and manage software packages written in Python. Many packages can be found in the default source for packages and their dependencies — Python Package Index (PyPI).[4]
Python 2.7.9 and later (on the python2 series), and Python 3.4 and later include pip (pip3 for Python 3) by default.[5]
pip is a recursive acronym for "Pip Installs Packages".[6]

Command-line interface[edit]
An output of
pip install virtualenvMost distributions of Python come with pip preinstalled. If pip is missing, it can be installed through the system package manager or by invoking cURL, a client-side data transfer tool:
curl https://bootstrap.pypa.io/get-pip.py | python
One 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.[4] 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
