bytes()

Theory

152/268

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

bytes() — output — b'A'. bytes is raw binary data.

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

Exam tip

Call bytes() once and say what prints.

# bytes()
print(bytes("A", "utf-8"))

bytes() — output: b'A'. bytes is raw binary data.
