abs()

Theory

148/268

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

abs() — output — 12 then 3.5. abs drops the sign.

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

Exam tip

Call abs() once and say what prints.

# abs()
print(abs(-12))
print(abs(3.5))

abs() — output: 12 then 3.5. abs drops the sign.
