The rsplit() method was a good idea; it will work.  So exactly what did 
you try and what about it did not work.  How are you stuck going from 
your partial answer to a complete one?

While you're at it, you need to consider at least two more cases

HELLO.txt                    #should return ""
HELLO_and_____goodbye        #should return "HELLO_and____"
