   That's just your first error.
(Also, you shouldn't have anything but Node items in
nodeTable, so you don't need the "node != 0".)

   The biggest problem is at

    Those are variables of the entire class.  Every
instance of Node shares the same variables. You
need

class Node:
    def __init__(self) :
        self.distFromSource = infinity
        self.previous = invalid_node
        self.visited = False
