range()

Theory

179/268

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

range() — output — [1, 2, 3, 4]. Stop 5 is exclusive.

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

Exam tip

Call range() once and say what prints.

# range()
print(list(range(1, 5)))

range() — output: [1, 2, 3, 4]. Stop 5 is exclusive.
