What is PIP?

PIP is a package manager for Python. It allows you to install and manage additional libraries and dependencies that are not included in the standard Python library.

What is a Package?

A package in Python is a collection of modules. Modules are individual Python files that contain functions, classes, and variables. Packages are directories of Python modules that include an __init__.py file.

Checking if PIP is Installed and Installing It

To check if PIP is installed and to install it if it is not, follow these steps:

  1. Check if PIP is installed:
    • Open your command prompt or terminal.
    • Type the following command and press Enter:
    • If PIP is installed, you will see a version number.
