What is PIP?

The standard package installer for Python, used to install and manage third-party libraries from PyPI.

PIP (Pip Installs Packages) downloads and installs packages from the Python Package Index (PyPI). Basic commands include pip install package_name, pip uninstall, pip list, and pip freeze.

Best practices include using virtual environments, pinning versions in requirements.txt, and using pip install --upgrade to update packages.
