Can you explain what a package manager pip is and what it is used for in Python?

pip is the standard package manager for Python, used for installing, updating, and managing third-party libraries and packages. With pip, you can easily add dependencies from the PyPI (Python Package Index) repository to your project without manual downloading and configuration.

Example of installing a package:

pip install requests

This will install the requests library, which is commonly used for HTTP requests.

Thus, pip simplifies working with external modules and helps keep the project up to date.
