How to replace characters in a string?

Hi,
Thanks for this!
So, is there a copy function/method that returns a MutableString like in objective-C? I’ve solved this problems before in a number of languages like Objective-C and AppleScript.
Basically there is a set of common characters that need “normalizing” and I have a method that replaces them in a string, so:
myString = [myString normalizeCharacters];
Would return a new string with all the “common” replacements applied.
Since the following gives an error :
myString = 'Hello'
myNewstring = myString.replace(myString,'e','a’)
TypeError: 'str' object cannot be interpreted as an integer
I can’t see of a way to do this in Python?
All the Best
Dave
