lstrip()

lstrip 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.

lstrip() — output — Asha (left spaces gone).

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

Exam tip

Call lstrip on one real word and say what prints.

Example

# lstrip()
print("  Asha".lstrip())

lstrip() — output: Asha (left spaces gone).

Short notes

Deflstrip works on str.
Rulelstrip usually returns a new string.
Traplstrip does not change the original string in place.
