How can I automatically update my class variables and lists using a child class?

Question

I need to update my Game lists and variables in the Game's init function from my Troop class.

# trying to make a game
# here is a quick summary of what I am trying to accomplish

class Game(object):
    def __init__(self):
        self.var1 = 0
        self.xlist = [1, 2, 3]
        self.ylist = [6, 5, 4]
    def mainloop(self)
        for x in range(0, len(self.xlist))
            t = Troop(self.xlist[x], self.ylist[x])

class Troop(Game):
    def ally(self, x, y):
        x += 1
      # ^--v these formulas are more complex in the game
        y += 1

      # v-- what I need to update from Troop class
      # var1, xlist, and ylist
        # code code code
        # code code code

The Troop class basically makes a copy of these variables and lists and changes only them. They are not updating correctly for my full game.

Your problem is one of class design. There is no way for _any_ class to access an instance variable without, well, creating an instance - you could maybe try some ugly hack with `super()`, but your code will simply look silly and hard to read. Instead, change your design: make your `Game` instance variables into class variables instead. Then you can access them from anywhere. — Akshat Mahajan, Jun 20 '16 at 04:07
but `var1`, `xlist`, `ylist` aren't class objects, they are instance objects i.e. instance variables. — juanpa.arrivillaga, Jun 20 '16 at 04:08
