You should update and return join_sentence and leave sentence unchanged after lowercasing it.
The default behavior of str.split() involves removing all whitespaces. You might want to try that out:
>>> s = ' hello there '
>>> s.split(' ')
['', 'hello', '', '', '', 'there', '', '', '']
>>> s.split()
['hello', 'there']
>>>
