Easy to find out: import doctest and see for yourself:

>>> import doctest
>>> doctest.ls
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'ls'

You found the ls() function in a docstring from Zope. The doctest seems 
to be testing ls(). That suggests to me that ls() is defined in Zope, not 
doctest.

Why do you ask?
