Run real Python, instantly
A full editor and console in every code exercise. Run as often as you like, then submit against hidden tests. No setup, no installs.
Feedback that explains itself
Every wrong answer tells you what was expected, what you got, and why it matters. Hints cost a little XP. Solutions are always there if you need them.
Progress you can measure
XP per exercise, levels with titles from Novice to Architect, daily streaks and a 12-week activity map. Ten minutes a day adds up.
