Python Tuples and Sets
Tuples and sets are often treated as secondary data structures behind lists and dicts, but they each solve specific problems that the other types cannot. Tuples provide immutable sequences for fixed data, function returns, and dict keys. Sets provide O(1) membership testing and mathematical set operations.
This collection covers both types, their guarantees, and the immutability concepts that connect them.
