bytes() — Python Technical Interview Questions & Answers

bytes()

bytes()

  • 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).

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