startswith(str,beg=0,end=len(str)) — Python Technical Interview Questions & Answers

startswith(str,beg=0,end=len(str))

startswith(str,beg=0,end=len(str))

  • startswith 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.
  • startswith(str,beg=0,end=len(str)) — output: True.
  • Fresher trap: writing s.startswith() and expecting s to update. Strings are immutable. Write s = s.startswith(...) if you need the new value (when it returns a string).

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