You don't need the module object for this. MY_MODULE.__doc __ is the
same as accessing __doc__ directly.

If you really need the current module object use sys.modules[__name__]

How about this:

# demo of accessing the docstring:

"""
This is a test.

Had this been a real document, it would have said something.
"""


if __name__ == '__main__':
import __main__
print __main__.__doc_ _

You are already inside the module, so an unqualified name will refer
to module globals unless it's being used in some local scope that has
a binding shadowing the global name.
