The question Carl's code was in answer to was, slightly paraphrased:
"Is it possible to get a *module*'s docstring from within the module
itself?"
The question had nothing to do with *function* docstrings.

The interactive interpreter environment also isn't quite a true
module, so you can't give it a docstring or really test the relevant
feature there. Try this instead:
$ cat test.py
"""I am the docstring of the `test` module!"""

print("This module's docstring is:", __doc__)
$ python test.py
This module's docstring is: I am the docstring of the `test` module!
$

Cheers,
Chris
