CodeRaft

CodeRaft teaches Python to complete beginners, one small step at a time. Read a short explanation, write real code, run it, and get friendly feedback on exactly what to fix. LEARN BY DOING Every lesson pairs a clear explanation and example with three coding exercises and a quick quiz. Hints go from gentle nudges to almost the answer, so you're never stuck. FEEDBACK THAT ACTUALLY HELPS Made a mistake? CodeRaft spots the common ones and tells you what went wrong in plain language, like "Your loop is still printing each number. Replace print(i) with total = total + i." Errors look just like real Python's, with a beginner-friendly tip underneath. FOUR COURSES - Python Fundamentals: printing, variables, strings, numbers, if statements, for and while loops, functions, lists and dictionaries. - Python Projects: combine what you know into small programs, like a shopping receipt, FizzBuzz, a grade book, a word counter, a to-do list and a guessing game. - Object-Oriented Programming: classes and objects, methods, __str__, objects working together, inheritance, super() and polymorphism. - Blind 75: the 75 classic coding interview problems, grouped by topic (arrays, dynamic programming, graphs, trees and more), each with hints, tests, a complexity check and a step-by-step solution walkthrough. A REAL CODE EDITOR Syntax highlighting, line numbers, smart indentation and a key bar with the symbols Python needs, built for typing code on an iPhone. PLAYGROUND Write and run any Python you like, with nothing graded. Start from ready-made examples or a blank page. STAY MOTIVATED Earn XP, level up, keep a daily streak and track your progress across every course. Finished lessons have a review mode with key points and your own solutions. PRIVATE BY DESIGN No account, no ads, no tracking. Your code runs on your iPhone and your progress never leaves it.
