reversed() — Python Technical Interview Questions & Answers

reversed()

reversed()

  • reversed() is built into Python. You do not import it. Freshers only need one honest call and the printed result — not a long definition.
  • reversed() — output: [3, 2, 1] then ahsA.
  • Wrong type often raises TypeError. Empty values matter for bool/all/any. Don’t mix reversed up with a similar name (sorted vs sort, int vs float).

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

Code Examples for reversed()
