The pip3 is the official Python package manager in order to install 3rd party modules. Python provides a lot of modules and libraries by default but as a popular programming language, there are also a lot of 3rd party modules and libraries. The pip3 is created to manage these modules or libraries by searching, installing, updating, removing them. The pip3 command can be used with Python installation which can be Windows, Ubuntu, Debian even MacOSX. In this tutorial, we examine how to install pip3 for different operating systems and platforms.
