Good questions

Do I need an account?+

How long is each course?+

Between 10 and 15 days. Each day takes about 20–30 minutes.

Do I need to install anything?+

No. Python code runs in your browser using WebAssembly. Install Python locally whenever you're ready.

What if I miss a day?+

Nothing breaks. Days are a pace, not a deadline. Pick up wherever you left off.

Start with one day.
