rpartition() — Python Technical Interview Questions & Answers

rpartition()

rpartition()

  • rpartition is a string helper. You call it on text like "Asha" or "banana". It gives a new string (or a number/True-False). The old string does not change unless you assign the result back.
  • rpartition() — output: ('a-b', '-', 'c'). Last -.
  • Fresher trap: writing s.rpartition() and expecting s to update. Strings are immutable. Write s = s.rpartition(...) if you need the new value (when it returns a string).

Technical Interview Tip: Call rpartition on one real word and say what prints.
