partition() — Python Technical Interview Questions & Answers

partition()

partition()

  • partition 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.
  • partition() — output: ('Asha', '-', 'Pune').
  • Fresher trap: writing s.partition() and expecting s to update. Strings are immutable. Write s = s.partition(...) if you need the new value (when it returns a string).

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