How the labs work
Python Labs are hands-on coding challenges that take you from your first print() to classes, generators, algorithms and complete projects.
Every lab runs Python right in your browser, so there is nothing to install. For each lab:
- Read the task, the input and output rules, and the example.
- Write your code in the editor and press Run to try it.
- Press Check to test it against hidden test cases. Your output must match exactly.
- Stuck? Read the hints, then open Show solution for a full explanation.
