Nice kata. Smirked once I've realized I was focusing too much on the unnecessary part.

This is an interesting kata, but basically unsolvable unless for some reason you already know the "trick" of it. A hint in the description to point experimentation in the right direction would be helpful.

I'll fix it tonight.

not blocking, could be added as suggestion

.

I think it's fine in this case, as it specifally is meant to teach us a specific feature in Python.

The code length could be increased. Currently, it seems like there is only one possible solution.

Either way, the correct way to restrict imports should be used. Maybe not as issue, but as suggestion, if imports don't get the job done anyhow. Or the restriction should be lifted.

IDK if there's a way to solve it with imports in fewer than 48, the shortest way I've found to bypass the check has exactly 48.

Imports are prohibited

You don't enforce this the correct way. Use ast
