Your question is Lists vs Tuples. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
What are lists and tuples, and what is the key difference between them? Explain how each behaves in Python, including mutability, ordering, and typical use cases. Give a small example and mention any important caveat about tuple contents.
Scope: Python 3 built-in list and tuple types. The interviewer is checking whether you can distinguish mutable and immutable sequence containers and apply that distinction to practical code.
