Which of the following is true about tuples in Python

Question

BlackTom AI · Accepted Answer

To evaluate the statements about Python tuples, I’ll examine each claim in turn and connect it to how tuples actually behave in Python.
Option A: 'Tuples are immutable and indexed by key' This is mixing two concepts incorrectly. Tuples are indeed immutable, but they are not indexed by a key (like a dictionary); they are ordered collections where elements are accessed by their position. The 'indexed by key' part makes this statement false.
Option B: 'Tuples are immutable and indexed by position (number)' This combines the correct ideas: tuples cannot be changed after creation (immutable), and elements are accessed by their position in the sequence (0-based index). This matches Python’s tuple semantics.
Option C: 'Tuples are mutable and indexed by key' This is false on two counts: immutability is a defining feature of tuples, and indexing by a key is not how tuples are accessed. Dictionaries use keys, but tuples rely on numeric indices.
Option D: 'Tuples are mutable and indexed by position (number)' Again, the mutability part is incorrect for tuples; they are immutable, so this statement is false despite the correct notion of indexing by position.
In summary, the only statement that accurately describes Python tuples is the one stating they are immutable and indexed by position, while the others misstate either mutability, indexing mechanism, or both.
