HowWhat happens inside

Why they askShows real use

yield pauses the function and returns a value to the caller, preserving local state.

Why interviewers care about Generators:

Generators questions separate people

Keep it short, concrete,

Stay structured

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

Close cleanly

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

1
yield pauses the function
and returns a value to the caller, preserving local state.
2

just after that yield.
3
A function with yield
returns a generator object immediately when called, not the yielded values yet.
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.

Here's a short line you can speak, broken into clear beats:
