rsplit(sep=None, maxsplit = -1) — Python Technical Interview Questions & Answers

rsplit(sep=None, maxsplit = -1)

rsplit(sep=None, maxsplit = -1)

  • rsplit 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.
  • rsplit(sep=None, maxsplit = -1) — output: ['a-b', 'c']. Split from the right, max 1.
  • Fresher trap: writing s.rsplit() and expecting s to update. Strings are immutable. Write s = s.rsplit(...) if you need the new value (when it returns a string).

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