 >>> print splitext.__doc__
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'splitext' is not defined
>>> print slices.__doc__
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'slices' is not defined
>>> print slices._doc_
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'slices' is not defined
