Explain Python tuples and typical usage

Q: Explain Python tuples and typical usage

This question evaluates a candidate's understanding of Python tuples, covering core properties such as ordering, immutability, and hashability, and compares tuples to lists in syntax, available operations, and performance characteristics.

Question

You are asked some Python fundamentals.

What is a tuple in Python? Describe its key properties (e.g., ordering, mutability, hashability).
How does a tuple differ from a list in terms of:
- syntax,
- mutability and available operations,
- typical use cases,
- performance or memory characteristics?
Give a few concrete examples of when you would prefer to use a tuple rather than a list (for example, in function returns, as dictionary keys, or to represent fixed-size records).
