Python Paths
Learn Python one small program at a time. Each step asks for one thing — “ask for 3 marks and print the average” — and is checked the moment you press Run the tests, including tests you cannot see. Steps are grouped into blocks, each linked to the notes that teach it, and the site remembers where you stopped.

How the checking works
- Your program runs in real Python in your browser. Each test gives it some inputs and compares what it prints, line by line, with the answer.
- Some tests are hidden, so a program that only prints the examples will not pass. Where a step teaches a construct (a for loop, match-case, a function), using it is checked too.
- A step is done when every check passes. Your best score counts towards your XP and follows your account to other devices.
- Stuck? Ask Z for a hint on the failing test, or open the model answer after two tries.
