How to access a function inside a function?

Question

I am wondering how I can access a function inside another function. I saw code like this:

>>> def make_adder(x):
      def adder(y):
        return

I'm not sure this helps, but you can use the __call__ boilerplate to simulate the behavior you're looking for. For example:

class MakeAdder:
    def __init__(self, x):
        self.x = x

    def __call__(self, y):
        return self.x + y



a = MakeAdder(5)
a(10)
