Pip Package Manager

Pip is the standard package manager for the Python programming language, used to install and manage software packages that are not part of the Python standard library. As a command-line tool, it simplifies the process of finding, downloading, and installing libraries and their required dependencies from the central Python Package Index (PyPI). By automating dependency management, often through a `requirements.txt` file that lists a project's dependencies, Pip is essential for creating reproducible development environments and ensuring that projects can be easily set up and run on different machines.
