A very small piece of it

This is the lesson shell from the early build, with the real editor chrome and three real lessons in it. It’s a tease, not the product — but nothing here is a mockup either.

Lesson four of the Python track. You’ve seen a list. Now you make the computer do something with every item in it, which is the moment the whole thing clicks for most people.

Task

Print every chore in the list, then mark it done.

Being honest

What’s missing from this preview

Four things you’d notice immediately if we handed you the real thing today. They’re the reason we haven’t.

  • No accountsSo nothing saves yet. Refresh and it’s gone.
  • No error teachingIt runs your code. It doesn’t yet explain why it broke.
  • No mobile editorTyping code on a phone keyboard is its own project.
  • No hintsThe bit where it notices you’re stuck is still on paper.
