How to replace characters in a string?

[Dave]

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
