What You Need Before Starting

Before we write any Python code, you need to install Python on your computer. You only do this once, and you’re ready to code forever.

How to Install Python

Go to https://python.org and download the latest version of Python.
Run the installer on your computer.
IMPORTANT: Check the box that says "Add Python to PATH" before clicking Install.
Complete the installation process and restart your terminal or command prompt.

Verify Installation
