Feed your brain. Grow the snake. Learn algorithms by writing real Python — on your phone. Python Challenge is a single path of original coding challenges, from your first `return a + b` to N-Queens, edit distance and Dijkstra. Every solution runs on-device in real Python and is checked against hidden tests, so passing means it actually works. WRITE REAL CODE • A coder keyboard built for Python: tab, snippets, brackets, quotes, undo • Instant feedback with named tests, expected vs actual output • Some levels enforce rules (no sorted(), recursion required) so you learn the technique, not the shortcut LEARN THE RIGHT WAY • Three-tier hints from PySnake, your slightly sardonic mentor • Curated solutions after you solve: naive vs optimal, time and space complexity • Topics: strings, lists, sorting, searching, recursion, dynamic programming, data structures, graphs, heaps, bit tricks, grids, greedy, intervals, math STAY MOTIVATED • One path, no shortcuts: easy → medium → hard, with performance tests on the hard ones • XP, levels, daily streaks and ten badges • Six themes, dark and light PRIVATE BY DESIGN • Works fully offline, no account, no ads, no tracking — your code and progress stay on your device. Only anonymous usage statistics are sent.
