pip
In plain terms
The standard package manager for Python.
Going deeper
pip installs Python packages from the Python Package Index (PyPI) and manages project dependencies. It's the default way to add Python libraries.
Under the hood
Often paired with virtual environments and requirements.txt; doesn't lock by default (pip-tools/Poetry help).
Examples
pip install, requirements.txt, PyPI, virtual environments, Python libraries.
Think of it like...
Like an app store for Python libraries you install with one command.
