These tutorials are designed for students, teacher or parents who want to learn the basics of python programming. Each tutorial explains the key concepts you need to understand then gives three types of free, interactive activities:
Try It
See a simple example and try out some simple challenges to tweak the codeDebug It
Boost your confidence in debugging by solving common mistakesExtend It
Stretch your understanding by applying what you’ve learnt in a more open-ended challenge
