pack1, price1 = 50, 24.59
pack2, price2 = 25, 11.99

class result:
    def __init__(self,pack,price):
        self.pack = pack
        self.price = price

    def set_pack(self):
        return self.pack
    def set_price(self):
        return self.price

    def get_result(self):
        return self.price / self.pack


a = result(pack1,price1)
b = result(pack2,price2)

if a.get_result() < b.get_result():
    print('pack1 has the better pack2')
else:
    print('pack2 has the better pack1')
