delattr() — Python Technical Interview Questions & Answers

delattr()

delattr()

  • delattr() is built into Python. You do not import it. Freshers only need one honest call and the printed result — not a long definition.
  • delattr() — output: True. delattr removes an attribute; here we only check hasattr.
  • Wrong type often raises TypeError. Empty values matter for bool/all/any. Don’t mix delattr up with a similar name (sorted vs sort, int vs float).

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