bool() — Python Technical Interview Questions & Answers

bool()

bool()

  • bool() is built into Python. You do not import it. Freshers only need one honest call and the printed result — not a long definition.
  • bool() — output: False then True. 0 is falsy; non-empty string is true.
  • Wrong type often raises TypeError. Empty values matter for bool/all/any. Don’t mix bool up with a similar name (sorted vs sort, int vs float).

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

Code Examples for bool()
