The Pip command is a tool for installing and managing Python packages, such as those found in the Python Package Index. With the help of pip you can also install the package of particular version. Most importantly pip has a feature to manage full lists of packages and corresponding version numbers, possible through a “requirements” file. It performs the same basic job as easy_install, but with some extra features.
