Well, on second thought it's not quite this unless it's a 1:1 mapping.
Point remains valid, though, I think.

However, some quick timing shows that translate has a very
high penalty for missing characters and is a tad slower any way.
Really, though, there sh

I have some code that I want to simplify. I know that a for-loop would
work well, but can I make re.sub perform all of the below tasks at once,
or can I write this in a way that is more efficient than using a for-loop?
DATA = re.sub(',', '', 'DATA')
DATA = re.sub('\'', '', 'DATA')
DATA = re.sub
