Christopher learned Python to automate his daily tasks as a system administrator.

Learn Effectively With Feedback

The fastest way to learn any skill is with rapid feedback. Ideally an experienced programmer would provide this feedback, telling you right away whether your code is correct, and if not, how to fix it. Our automated system takes the place of this programmer, analyzing your code, checking it for correctness, and providing instant feedback.



Acquire knowledge through examples, definitions, and hands-on experimentation.


Master your new knowledge with practical exercises.


Test your newly acquired skills with intriguing coding challenges.

Anyone can learn how to code

With clear instructions, practical exercises, and immediate feedback, anyone can go from non-technical to knowing how to program.
"You can definitely jump in and just get started writing code, learning as you go."
