What is a docstring?
PICTURE THIS: HOW TO EXPLAIN IT
IdeaPython
HowWhat happens inside
Why they askShows real use
Simple meaning
A string literal documenting a module, class, or function.
WHY — Python instead of guessing?
Why interviewers care about Python:
Python questions separate people
who only read docs from people who shipped.
Keep it short, concrete,
and tied to Python work.
Stay structured
Name the idea, why it exists, then one short example.
Close cleanly
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:
- 1A string literal documenting
a module, class, or function.
- 2Why it exists
Tools extract them.
- 3I keep them up
to date with behavior.
- 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.
