I am making a game where the user should write answer (the question() function). In the question function I am using variables of 1 and 0 to get the information if the user's answer is wrong or correct. I am also using variables of 1 and 0 to see if the user has answered the questions.

def main():

    menu()

    anv_val = ber_val()

    val(anv_val)



def menu():

    print("1. game")

    print("2. stat")

    print("3. end")



def ber_val():

    val = input("Your choice: ")

    while val not in ["1", "2", "3"]:

        print("Print 1, 2 or 3.")

        val = input("Your choice: ")

    return val



def val(anv_val):

    if (anv_val == "1"):

        res = game()

        return res

    elif (anv_val == "2"):

        res = game()

        return stat(res)

    else:

        return end()



def question(quest, solu):

    print(quest)

    answer = input("Your answer: ")

    a_s = 1

    a_f = 0

    while (answer != solu):

        a_f = 1

        print("Try again")

        answer = input("Your answer: ")

    print("Correct!")

    a_f_s = [a_f, a_s]

    return a_f_s



def game():

    a_1 = question("Your name?", "Ricky")

    a_2 = question("Your name?", "Rong")

    a_3 = question("Your name?", "Bolly")

    sum_f = a_1[0] + a_2[0] + a_3[0]

    sum_s = a_1[1] + a_2[1] + a_3[1]

    sum_all = [sum_f, sum_s]

    return sum_all, main()



def stat(res):

    print("Questions you answered: " + str(res[1]))

    print("Wrong times: " + str(res[0]))

    return main()



main()

Now to my problem. In the function game(), I want to return the variable called a_f_s, AND USE the information (the information is number of error and answered questions) in my function stat(). But the problem is that in the function val(anv_val) - if the user prints "2", the function game() will run, but I want the stat() to run. I am a little bit confused.

I appreciate all the help!

I've added a global variable end_game, to control a while loop in main(). This way, you won't need to keep calling game(), thus simplifying your program logic. Notice that game() does not return a call to main() now.

I also made res a global variable that is only modified when game() is called. In stat(), the global res is used to print stats if it is not None.

end_game = False

res = None



def main():

    while not end_game:

        menu()

        anv_val = ber_val()

        val(anv_val)



def menu():

    print("1. game")

    print("2. stat")

    print("3. end")



def ber_val():

    val = input("Your choice: ")

    while val not in ["1", "2", "3"]:

        print("Print 1, 2 or 3.")

        val = input("Your choice: ")

    return val



def val(anv_val):

    global end_game, res

    if (anv_val == "1"):

        res = game()

    elif (anv_val == "2"):

        stat()

    else:

        end_game = True





def question(quest, solu):

    print(quest)

    answer = input("Your answer: ")

    a_s = 1

    a_f = 0

    while (answer != solu):

        a_f = 1

        print("Try again")

        answer = input("Your answer: ")

    print("Correct!")

    a_f_s = [a_f, a_s]

    return a_f_s



def game():

    a_1 = question("Your name?", "Ricky")

    a_2 = question("Your name?", "Rong")

    a_3 = question("Your name?", "Bolly")

    sum_f = a_1[0] + a_2[0] + a_3[0]

    sum_s = a_1[1] + a_2[1] + a_3[1]

    sum_all = [sum_f, sum_s]

    return sum_all



def stat():

    if res is not None:

        print("Questions you answered: " + str(res[1]))

        print("Wrong times: " + str(res[0]))

    return



main()

As a bonus, here is a simpler way I would write your code:

def main():

    res = None



    while True:

        print_menu()

        choice = get_choice()



        if (choice == "1"):

            res = game()

        elif (choice == "2"):

            stat()

        else:

            return



def print_menu():

    print("1. game")

    print("2. stat")

    print("3. end")



def get_choice():

    val = input("Your choice: ")

    while val not in ["1", "2", "3"]:

        print("Print 1, 2 or 3.")

        val = input("Your choice: ")

    return val



def question(quest, solu):

    print(quest)

    answer = input("Your answer: ")

    a_s = 1

    a_f = 0

    while (answer != solu):

        a_f = 1

        print("Try again")

        answer = input("Your answer: ")

    print("Correct!")

    a_f_s = [a_f, a_s]

    return a_f_s



def game():

    a_1 = question("Your name?", "Ricky")

    a_2 = question("Your name?", "Rong")

    a_3 = question("Your name?", "Bolly")

    sum_f = a_1[0] + a_2[0] + a_3[0]

    sum_s = a_1[1] + a_2[1] + a_3[1]

    sum_all = [sum_f, sum_s]

    return sum_all



def stat():

    if res is not None:

        print("Questions you answered: " + str(res[1]))

        print("Wrong times: " + str(res[0]))

    return



main()

Two observations :

1. 
   Questions you answered: will always print the same result for all as the program does not proceed until the user has answered all questions.


2. You should use a_f = a_f + 1 to increment the count of false answers.
