What are *args and **kwargs?
PICTURE THIS: FLEX VS GRID
Flex — one line
Grid — rows + cols
Simple meaning
args collects extra positional arguments as a tuple.
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:
- 1args collects extra positional
arguments as a tuple.
- 2*kwargs collects extra keyword
arguments as a dict.
- 3They help write flexible
wrappers and decorators.
- 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.
