int() — Python Technical Interview Questions & Answers

int()

int()

  • int() is built into Python. You do not import it. Freshers only need one honest call and the printed result — not a long definition.
  • Output: 22 then 3. int() truncates toward zero.
  • Wrong type often raises TypeError. Empty values matter for bool/all/any. Don’t mix int up with a similar name (sorted vs sort, int vs float).

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

Code Examples for int()

Example
