Stay structured

Name the idea, why it exists, then one short example.

Close cleanly

End with when you use it and one common pitfall.

Before you speak the answer, walk the interviewer through these steps:

1

and makes yield return that value inside the function.
2
The first resume must
still be next() or send(None).
3
This two-way channel is
the old coroutine protocol, now mostly replaced by async/await.
4
Give an example
One tiny concrete case you can say aloud.
5
Common mistake
What juniors usually get wrong.
6
Close
When you pick this over the alternative.
