memoryview()

Theory

172/268

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

memoryview() — output — 65. Byte 0 of b'A' is 65.

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

Exam tip

Call memoryview() once and say what prints.

# memoryview()
v = memoryview(b"AB")
print(v[0])

memoryview() — output: 65. Byte 0 of b'A' is 65.
