Expected behavior

Hi, guys. I come across one global variable that used in class method. I think using instance attribute would be better !

    def show_data(self):
        show_list = []
        for i in range(1, N + 1):  ==> should using self.N instead of N !
            show_list += [self.query(i, i)]
        print(show_list)

Actual behavior

    def show_data(self):
        show_list = []
        for i in range(1, self.N + 1):  
            show_list += [self.query(i, i)]
        print(show_list)
