dict.clear()

Theory

259/268

dict.clear() works on a dictionary — labelled data like marks["Asha"] = 90. Keys map to values. Loop with .items() when you need both.

dict.clear() — output — {}.

Trap for dict.clear() — writing d[missing] in a viva. Prefer get when the key might not exist.

Exam tip

get vs [] — one sentence + tiny dict of marks.

# dict.clear()
d = {"a": 1}
d.clear()
print(d)

dict.clear() — output: {}.
