reversed()

Theory

178/268

reversed() is built into Python. You do not import it. Freshers only need one honest call and the printed result — not a long definition.

reversed() — output — [3, 2, 1] then ahsA.

Wrong type often raises TypeError. Empty values matter for bool/all/any. Don’t mix reversed up with a similar name (sorted vs sort, int vs float).

Exam tip

Call reversed() once and say what prints.

# reversed()
print(list(reversed([1, 2, 3])))
print("".join(reversed("Asha")))

reversed() — output: [3, 2, 1] then ahsA.
