Checkpoint

One last thing before we move on. Same surface as a write step — but the lesson doesn't complete until this passes.

One last thing. AI wrote a function tag_user that's supposed to return a new user dict with one extra tag, leaving the original user alone. Right now it mutates the input.

Expected output:

original tags: ['pm']
tagged tags: ['pm', 'vip']
