Help on built-in function rsplit:
rsplit(...)
 S.rsplit([sep [,maxsplit]]) -> list of strings
 Return a list of the words in the string S, using sep as the
 delimiter string, starting at the end of the string and working
 to the front. If maxsplit is given, at most maxsplit splits are
 done. If sep is not specified or is None, any whitespace string
 is a separator.
 >>> step_two = test.rsplit(None, 1)
 >>> step_two
['This is a', 'test']
 >>>
 >>> step_two[1]
'test'
 >>>
