Replacing one character of a string in python

Question

In python, are strings mutable? The line someString[3] = \"a\" throws the error

TypeError: \'str\' object does not support item assig

Answer 1

Python strings are immutable, which means that they do not support item or slice assignment. You'll have to build a new string using i.e. someString[:3] + 'a' + someString[4:] or some other suitable approach.
