CodeRaft 1.0

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.
