id() — Python Technical Interview Questions & Answers

id()

id()

  • id() is built into Python. You do not import it. Freshers only need one honest call and the printed result — not a long definition.
  • id() — output: True. id is the object identity (memory-ish id).
  • Wrong type often raises TypeError. Empty values matter for bool/all/any. Don’t mix id up with a similar name (sorted vs sort, int vs float).

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