chr()
chr() is built into Python. You do not import it. Freshers only need one honest call and the printed result — not a long definition.
chr() — output — A. 65 is Unicode for A.
Wrong type often raises TypeError. Empty values matter for bool/all/any. Don’t mix chr up with a similar name (sorted vs sort, int vs float).
Exam tip
Call chr() once and say what prints.
