Question

I am trying to figure out how to put a define function inside a define function inside of a class. Python code of what I want to do:

class Guy():
    def move(self):
        def left(self):
            //compute
        def right(self):
            //compute
        def up(self):
            //compute
        def down(self):
            //compute

And then be able to call Guy.move.right() later on in the program. The interpreter gives me an error saying ‘Function has no attribute right’ or something like that. Is there any way to do this without having to bring my functions out of the move function and calling them Guy.right, Guy.left, etc.?

Answer 1

this is a bad way to code…

there is no way to call left function under Guy class since it is in the scope of move function, and unlike class, adding a function inside another function does not make it its attribute.

Until the inside function is a attribute of the outside function there is no way to call it using the name of the enclosing function

In case

def move():
    def left():

i.e. If there is only one function inside a function it is feasible to return left() from move function.

However in this case there are multiple functions inside move function scope.

You should look for something like a nested class and make move as a class rather than a function
