Функция не вызывается во время цикла

Question

Я создал функцию loss (), win () и draw (), чтобы изменить счет после событий. Проблема в том, что их не вызывают в то время, как l oop меняет счет и устанавливает его правильно , У меня были строки для каждого оператора if и elif, но я решил использовать функцию, чтобы сделать код короче и эффективнее.

    from random import randint
    print("Welcome to this game of rock paper scissors against the computer.")
    print("Good luck and have fun! Enjoy this game! ")
    print("To stop playing, type quit when the round ends.If you want to continue playing, press any key ")
    scoreH=0
    scoreAI=0
    Round=0

   def loss():
        scoreH=scoreH+0
        scoreAI=scoreAI+1
    def win():
        scoreH=scoreH+1
        scoreAI=scoreAI+0
    def draw():
        scoreH=scoreH+0
        scoreAI=scoreAi+0        

    x=True


    while x == True :
        # Choice

        print("3.Scissors")
        choice=input("Enter your choice: ").lower()
        IntChoice=randint(1,3)


        #Transforming AI_choice from an int to a string 
        if IntChoice == 1:
            AI_choice="rock"

Answer 2

Они действительно вызываются, но они изменяют локальную переменную внутри себя.

Чтобы изменить значения, сделайте что-то вроде этого:

def loss(scoreAI):
     return scoreAI+1


scoreAI = loss(scoreAI)

На самом деле, функции действительно просты и в некоторых случаях вы добавляете 0, что равносильно тому, что вы ничего не делаете, поэтому я бы не стал делать для этого функции. Это намного проще:

#Win
scoreH += 1

#Loss
scoreAI += 1

и вам ничего не нужно для розыгрыша.

Надеюсь, это поможет!
