How to print Docstring of python function from inside the function itself?

Question

I want to print the docstring of a python function from inside the function itself. for eg.

def my_function(self):
  \"\"\"Doc string for my function.\"\"\"
         


        

Answer 1

This works:

def my_function():
  """Docstring for my function"""
  #print the Docstring here.
  print my_function.__doc__

my_function()

in Python 2.7.1

This also works:

class MyClass(object):
    def my_function(self):
        """Docstring for my function"""
        #print the Docstring here, either way works.
        print MyClass.my_function.__doc__
        print self.my_function.__doc__


foo = MyClass()

foo.my_function()

This however, will not work on its own:

class MyClass(object):
    def my_function(self):
        """Docstring for my function"""
        #print the Docstring here.
        print my_function.__doc__


foo = MyClass()

foo.my_function()

NameError: global name 'my_function' is not defined
