capitalize() — Python Technical Interview Questions & Answers

capitalize()

capitalize()

  • capitalize 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.
  • capitalize() — output: Asha pune. First char upper, rest lower.
  • Fresher trap: writing s.capitalize() and expecting s to update. Strings are immutable. Write s = s.capitalize(...) if you need the new value (when it returns a string).

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