Python for kids, right in the browser

Why Python is a good first language

Python reads almost like English, so kids spend their time on ideas, not punctuation. It's also the real thing: the language behind a lot of science, data and AI work. What they learn here keeps being useful.

import random

secret = random.randint(1, 20)
guess = 0

while guess != secret:
    guess = int(input("Guess my number (1-20): "))
    if guess < secret:
        print("Higher!")
    elif guess > secret:
        print("Lower!")

print("You got it!")

That's a whole game in about a dozen lines. Paste it into a new Python project and press ▶ Run.

What makes it work for kids

• Nothing to installPython runs in the browser tab, even on a locked-down school Chromebook.
• Typing answersWhen a program calls input(), a text box appears right in the output.
• Errors that helpMistakes show in red with the line number, so kids learn to find their own bugs.
• Stop always worksPython runs in the background, so a runaway loop never freezes the page.
• More than one fileSplit a program into files and import them, like real projects do.
• Saved as they typeAnd every published version can be brought back.

A path through the Python projects

1. Castle Escape: a text adventure. Learn input(), loops, lists and dictionaries by adding rooms.
2. ChatBot Buddy: a rule-based chatbot that remembers your name and tells jokes. Teach it new things to say.
3. Secret Codes: encrypt messages with a Caesar cipher, then crack one without the key.
4. Rock Paper Scissors AI: a computer that learns your habits and predicts your next move.
5. ASCII Art Studio: giant banners and the Mandelbrot fractal, drawn with nested loops.
6. Probability Lab: roll dice 10,000 times and estimate π with random darts.
7. Maze Maker & Solver: generate a maze with depth-first search and solve it with breadth-first search.

Each project has a page explaining how its code works, settings to tweak and challenges to try.

For teachers and parents

Make a class (or a family), add kids by nickname, and assign any of these projects as a starter. Each kid gets their own copy, turns it in when they're done, and you review their code running next to a feedback box. How Python works in the editor →
