Implementing Stack with Python

Question

I am trying to implement a simple stack with Python using arrays. I was wondering if someone could let me know what\'s wrong with my code.

class myStack:

Your stack is an array...

class stacked(): # Nodes in the stack
    def __init__(self,obj,next):
        self.obj = obj
        self.next = next
    def getObj(self):
        return(self.obj)
    def getNext(self):
        return(self.next)

class stack(): # The stack itself
    def __init__(self):
        self.top=None
    def push(self,obj):
        self.top = stacked(obj,self.top)
    def pop(self):
        if(self.top == None):
            return(None)
        r = self.top.getObj()
        self.top = self.top.getNext()
        return(r)
