Multi-key sort with tuple

Question

Accepted Answer

The key function returns `(-score, name)`, so higher scores sort first (because negating flips the order) and ties break alphabetically. Alice and Carol both have score 90, so their negated scores are equal at -90. The tiebreaker is the name, and 'Alice' < 'Carol' alphabetically, so Alice comes first. `result[0]` is `('Alice', 90)`, and `result[0][0]` is `'Alice'`.
