encode()

encode 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.

encode() — output — b'A'.

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

Exam tip

Call encode on one real word and say what prints.

Example

# encode()
print("A".encode("utf-8"))

encode() — output: b'A'.

Short notes

Defencode works on str.
Ruleencode usually returns a new string.
Trapencode does not change the original string in place.
