This tutorial will guide you through installing pip for Python 3 (pip3) on Debian 12 using the apt package manager and provide an overview of basic pip functionalities.

Installing Pip on Debian

Since Python 2 is no longer supported (post January 1, 2020), we will focus on installing pip for Python 3.

1. Update Package Index Begin by updating your local package index:
