memoryview() — Python Technical Interview Questions & Answers

memoryview()

memoryview()

  • 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).

Technical Interview Tip: Call memoryview() once and say what prints.
