What is PIP and How Does it Work?

PIP, short for Python Package Installer, is a package management system that allows you to install and manage software written in Python. PIP is commonly used to manage Python-written program packages and their dependencies, making it an essential tool for Python developers. PIP works with PyPI (Python Package Index), a repository of Python binary packages, to facilitate the installation and management of Python plugins and software. With a simple Python command-line interface, PIP allows you to quickly and easily install, upgrade, and uninstall Python packages.
