如何自动生成包含嵌套函数的文档字符串？

Question

How to generate automatically docs for the c_nested function?

Background: I do code documentation for other developers and I would like to automatically generate a summary of all class methods included nested functions with short description (docstring).

When I run help(A) on class A I get:

Help on class A in module __main__:

class A(builtins.object)
 |  A(a)
 |  
 |  doc A
 |  
 |  Methods defined here:
 |  
 |  __init__(self, a)
 |      Initialize self.  See 
 |  
 |  b_method(self)
 |      doc b_method

Requested output: c_nested() with docstring: (Docs could be printed event with script, it doesn't need to be printed with pydoc help.)

Help on class A in module __main__:

class A(builtins.object)
 |  A(a)
 |  
 |  doc A
 |  
 |  Methods defined here:
 |  
 |  __init__(self, a)
 |      Initialize self.  See 
 |  
 |  b_method(self)
 |      doc b_method
 |
 |           c_nested()
 |                doc c_nested

Class example:

class A:
    """ doc A """
    def __init__(self,a):
        self.a = a

    def b_method(self):
        """ doc b_method """

        def c_nested():
            """doc  c_nested """
            pass

        return c_nested()

Local functions are not publicly visible, so their docstring won't be included in the help.

If you want the function to be shown in the help, make it a module-level function or a method of the class.
