[Tutor] how to reference a function itself when accessing its private functions?

[Tim Michelsen]

Dear Tutors and fellow pythonistas,
I would like to get access to the private methods of my function.

For instance:
Who can I reference the docstring of a function within the function itself?

Please have a look at the code below and assist me.

Thanks and regards,
Timmie

#### CODE ###

s = 'hello'

def show(str):
     """prints str"""
     print str

     return str



def show2(str):
	"""prints str"""
	print str
	d = self.__doc__
	print d

 >>> show2(s)
hello

<ipython console> in <module>()

<ipython console> in show2(str)

NameError: global name 'self' is not defined
