Remove part of strings

Hi,
I have been having this problem for some scripts and I need your help. I have a list of strings that contain numbers or letter witch I need to remove (in this case numbers). Is there a way to remove parts of strings without knowing hos many items they contain? In this case I would like to tell dynamo to "Remove all characters after “,”.

Some ways of doing it:
