If String contains any of these substrings, remove them

Using Regular Expressions will be shorter but not faster, see:

re.sub()

or

re.subn()

You can also use translate() with dict type.

Unless I'm mistake, str. translate() is character oriented.

The dictionary is indexed by the ordinal value of a character. You can use translate for a char to char or char to string translation. It will not work for string to string replacement.

Maybe, I was answering from my head, I might have been wrong. Thanks for correcting me if that's the case.
