Can one function have several decorators?
PICTURE THIS: STACK VS QUEUE
WHY — Decorators instead of guessing?
Why interviewers care about Decorators:
who only read docs from people who shipped.
and tied to Python work.
Name the idea, why it exists, then one short example.
End with when you use it and one common pitfall.
STEPS — What happens step by step?
Before you speak the answer, walk the interviewer through these steps:
- 1You stack them, and
Python applies the nearest decorator first, then the one above it.
- 2Order matters: @login_required above
@require_POST is not the same as the reverse if either short-circuits the request.
- 3How it works
Walk the main flow in 2–3 beats.
- 4Give an example
One tiny concrete case you can say aloud.
- 5Common mistake
What juniors usually get wrong.
- 6Close
When you pick this over the alternative.
EXAMPLE — See it in action
Here's a short line you can speak, broken into clear beats:
Note: Adapt this scaffold to your own project — keep it under 60–90 seconds.
Key takeaway
You stack them, and Python applies the nearest decorator first, then the one above it. Order matters: @login_required above @require_POST is not the same as the reverse if either short-circuits the request.
