A few things to keep nearby as you learn:

• The official docs at docs.python.org — accurate and complete (a bit dense, but the source of truth).
• This course's Run boxes — your fastest way to test an idea.
• An AI assistant for plain-English explanations (see the "AI assistants" lesson).
• Your own notes file. Each time something clicks, write it in your own words. You'll remember it far better.

When you get stuck — and everyone does — search the exact error message. Someone has almost certainly hit it before you.
