Evaluates understanding of Python data structures—specifically lists versus tuples—by probing concepts such as mutability and its implications, high-level performance and memory trade-offs, typical use cases, and hashability for use as dictionary keys.

In Python, what are the key differences between a list and a tuple?

Cover:

  • Mutability and implications
  • Performance and memory considerations (high level)
  • Typical use cases
  • Hashability and when tuples can be dictionary keys
  • One short code example illustrating an important difference
