Everytime I call a method I want the value to be decreased by 1

Is there a way I can decrease the value by 1 every time I call the method.

The code I tried is 

Class Testing:
    max_count = 5
    def update_count(self, reducebyone):
        actual_count = max_count
        updated_count = actual_count - reducebyone
        resetcount = updated_count
        print(actual_count)
        print(updated_count)
        print(resetcount)

obj = Testing()
obj.update_count(1)
obj.update_count(1)

The result im expecting is when the method called first time I expect the O/P to be : 5 4 4 And second time when the method is called I expect the O/P to be : 4 3 3 Can anyone help in this.

Yes there are plenty of ways to achieve this !

The easiest one would be to add self.max_count = updated_count after you compute updated_count. Also you need to access to max_count always using self.max_count

All your variables are local to the method. You will need to store the count state in the class or the instance. The way you invoke the method indicates you are after the latter:

class Testing:
    def __init__(self):
        self.count = 5

    def update_count(self, reducebyone):
        print(self.count)
        self.count -= reducebyone
        print(self.count)

>>> obj = Testing()
>>> obj.update_count(1)
5
4
>>> obj.update_count(1)
4
3

Is this is what you wanted? A loop I think would be better, but I don't know what are you trying to achieve.

class Testing:
    max_count = 5
    cur_count = max_count

    def update_count(self, reducebyone):
        self.cur_count -= reducebyone
        resetcount = self.cur_count
        print(self.max_count)
        print(self.cur_count)
        print(resetcount)

obj = Testing()
obj.update_count(1)
obj.update_count(1)

Output:

5
4
4
5
3
3
