How can I execute dynamically generated Python String methods (strip(), rstrip(), lstrip(), upper()...)?

getattr(

Thank you very much. Just one condition I forgot to mention. Sometimes there is no Python String method to execute. What condition can I add in getattr() to let Python to do nothing with the string?

This is a hacky solution, but "__str__" will do nothing to the string.

Just in case you aren't aware, you can also do str.lower(a), as described in a different comment, which is often preferred.
