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).

Exam tip

Call partition on one real word and say what prints.

Example

# partition()
print("Asha-Pune".partition("-"))

partition() — output: ('Asha', '-', 'Pune').

Short notes

Defpartition works on str.
Rulepartition usually returns a new string.
Trappartition does not change the original string in place.
