Trying to make a Matrix of nodes in Python

Hey /prog/rammers, I'm trying to make a Matrix of nodes in python.
so far I have a node class that reads as such:

class Node (object) :
   
    def __init__(self, value):
        self.north = None
        self.east = None
        self.south = None
        self.west = None
        self.value = value
       
    def getNorth(self):
        return self.north
       
    def getSouth(self):
        return self.south
       
    def getEast(self):
        return self.east
       
    def getWest(self):
        return self.west
       
    def getValue(self):
        return self.value


And a LinkedMatrix class that reads like this:

class LinkedMatrix(object):
   
    def __init__(self, x, y, defaultValue):
       
        ''' create a new matrix with x columns and y rows
        with default value default value'''
       
        self._xRows = x
        # x amt of rows
        self._yCols = y
        # y amt of columns
       
        base_node=Node(defaultValue)
        self.head = Node(defaultValue)
       
        self.mlist = []
        self.head.east=base_node
        self.mlist = [self.head]
        for number in range(self._yCols):
            base_node.east=Node(defaultValue)
            self.mlist = self.mlist + [base_node]
       
     
     
       
       
       
 Im thinking I should make a list of the nodes in python and then make a list of lists, but Im having trouble wording my code so that the nodes properly connect to each other, and I also am wondering how I can make their connections (north and south) work across different lists.

Help is very needed and would be very appreciated.
