Using Third-Party Libraries

PyPI

PyPI is the Python Package Index. It provides a central index of Python packages, any of which can be installed with a single command.

Not to be confused with PyPy, an alternative Python interpreter.

Installation

Use the pip command to install libraries into a virtual environment.

For example:

$ workon sysadmin # Activate virtualenv
(sysadmin)$ pip install ipython

If you really must install a library system-wide, please first look and see if a reasonable version of the library is available from your system’s package manager.
