[SOLVED] I cant call a class method in Python; AttributeError: 'check_class' object has no attribute 'check_1'

Issue

I want to check if the games have numbers in a particular key?

But i cant call the the class method check_1(), can you help me out?
It gives me ‘check_class’ object has no attribute ‘check_1’.

And do you have a idea how i can avoid the global variabel and the global fuction for the recursion, because its bad practice?

I am thankful for every suggestion to optimize the code, i am relatively new to programing.

from queue import Empty

class check_class :
    
    def __init__(self, dict1={}, dict2={}, dict3={}, dict4={}, dict5={}, dict6={}, dict7={}, dict8={}, dict9={}, dict10={}, dict11={}, dict12={}, dictionary_of_games ={}):
        self.dict1 = dict1
        self.dict2 = dict2
        self.dict3 = dict3
        self.dict4 = dict4
        self.dict5 = dict5
        self.dict6 = dict6
        self.dict7 = dict7
        self.dict8 = dict8
        self.dict9 = dict9
        self.dict10 = dict10
        self.dict11 = dict11
        self.dict12 = dict12
        self.dictionary_of_games = dictionary_of_games

        dictionary_of_games = [
        self.dict1,
        self.dict2,
        self.dict3,
        self.dict4,
        self.dict5,
        self.dict6,
        self.dict7,
        self.dict8,
        self.dict9,
        self.dict10,
        self.dict11,
        self.dict12
        ]

    global played_games_of_the_day
    played_games_of_the_day =[]

    global check_1
    def check_1(self, **kwargs):
        hht = kwargs.get("halbzeit_h_tore")
        hat = kwargs.get("halbzeit_a_tore")
        c = 1
        if hht == "-" and hat == "-":
            played_games_of_the_day.append(0)
            c += 1
            return check_1(self, self.dictionary_of_games[c])
        elif int(hht) == int and int(hat) == int :
            c += 1
            played_games_of_the_day.append(1)
            return check_1(self, self.dictionary_of_games[c])
        #if dict empty pass#
        elif Empty:
            pass
        
        for i in played_games_of_the_day:
            if all(x==0 for x in played_games_of_the_day):
                print("all zero")
            elif all(x==1 for x in played_games_of_the_day):
                print("all one")

b = check_class(a)
b.check_1(b.dictionary_of_games[0])

I’m getting an AttributeError: ‘check_class’ object has no attribute ‘check_1’

Solution

Putting global check_1 before the definition of the function in the class body will create a function in the global scope, not a method.

class A:
    global check_1
    def check_1(self):
        print('check_1')
    def check_2(self):    
        print('check_2')

Demo:

>>> 'check_1' in A.__dict__
False
>>> 'check_2' in A.__dict__
True
>>> check_1
<function __main__.check_1(self)>
>>> A().check_1()
[...]
AttributeError: 'A' object has no attribute 'check_1'
>>> A().check_2()
check_2

As to why you put global check_1 there, I have no idea.
