sorted()
sorted() is built into Python. You do not import it. Freshers only need one honest call and the printed result — not a long definition.
sorted() — output — [1, 2, 3] then ['A', 'a', 'h', 's']. New list, original unchanged.
Wrong type often raises TypeError. Empty values matter for bool/all/any. Don’t mix sorted up with a similar name (sorted vs sort, int vs float).
Exam tip
Call sorted() once and say what prints.
