complex() — Python Technical Interview Questions & Answers

complex()

complex()

  • complex() is built into Python. You do not import it. Freshers only need one honest call and the printed result — not a long definition.
  • complex() — output: (2+3j). Real + imaginary.
  • Wrong type often raises TypeError. Empty values matter for bool/all/any. Don’t mix complex up with a similar name (sorted vs sort, int vs float).

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