setattr()

Theory

200/268

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

setattr() — output — Asha. setattr writes an attribute by name.

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

Exam tip

Call setattr() once and say what prints.

# setattr()
class S: pass
s = S()
setattr(s, "name", "Asha")
print(s.name)

setattr() — output: Asha. setattr writes an attribute by name.
