Do I need to install Python to do these problems?

No. Your code runs in the browser on this page, so a phone or a school computer is enough. The first check takes a few seconds while Python loads; after that it is instant.

Which problem should I start with?

Set 1, Print & strings. The sets follow the order of the free lessons, so if a set feels hard, read the lesson linked on its card first and come back.

What happens if I get stuck?

After one try you can open a hint. After three tries you can see the solution. A problem you pass after seeing the solution is marked as such, so you know which ones to redo.

Is it free? Do I need an account?

All 60 problems are free and need no account. Your progress is saved in this browser only.
