Topic Relevance
Everything starts here. You can’t write Python code without installing Python first, and you can’t appreciate Python without understanding why it was designed the way it was.
Key insight: Python was intentionally designed to be readable. Its creator, Guido van Rossum, wanted a language that felt like reading English. That philosophy is why Python is the #1 recommended language for beginners worldwide.
