bin()

Theory

150/268

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

bin() — output — 0b1010. Binary text for 10.

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

Exam tip

Call bin() once and say what prints.

# bin()
print(bin(10))

bin() — output: 0b1010. Binary text for 10.
