Python: Data Structures

Python's built-in data structures are the foundation of almost every program you'll write. This quiz tests your understanding of lists, tuples, sets, and dictionaries — their syntax, behavior, and the performance trade-offs that determine which to choose in a given situation.

Questions cover mutability, indexing, membership testing, dictionary operations, and the difference between shallow and deep copies. These are the distinctions that separate programmers who write working code from those who write efficient code.

Whether you're preparing for a Python interview or levelling up your fundamentals, this quiz gives a clear picture of how well you know Python's core data structures.
