istitle()

istitle 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.

istitle() — output — True.

Fresher trap: writing s.istitle() and expecting s to update. Strings are immutable. Write s = s.istitle(...) if you need the new value (when it returns a string).

Exam tip

Call istitle on one real word and say what prints.

Example

# istitle()
print("Asha Pune".istitle())

istitle() — output: True.

Short notes

Defistitle works on str.
Ruleistitle usually returns a new string.
Trapistitle does not change the original string in place.
