Replacing one character of a string in python
python
Solution
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.
Problem
In python, are strings mutable? The line `someString[3] = "a"` throws the error TypeError: 'str' object does not support item assignment I can see why (as I could have written someString[3] = "test" and that would obviously be illegal) but is there a method to do this in python?
