和answer作为输入这是函数的代码：

    def question():
        print('question')
        print('A = ', answer1)
        print('B = ', answer2)
        print('C = ', answer3)
        print('D = ', answer4)
        answer = input('Remember, Case sensitive!\n')
    
        if answer == 'A':
            if correctanswer == 'A':
                print('Correct! Score +1')
                score = score + 1
                print('Score = ', score)
            else:
                print('Incorrect! The glowing device in my arm buzzed. The world around me started to pixelate. I felt a sharp zap in my arm and everything went black')
                print('Score - 1')
                score = score - 1
                print('Score = ', score)
                death.start()

                score = score + 1
                print('Score = ', score)
            else:
                print('Incorrect! The glowing device in my arm buzzed. The world around me started to pixelate. I felt a sharp zap in my arm and everything went black')
                print('Score - 1')

如您所见，除了减一分外，没有死亡惩罚。我收到语法错误： UnboundLocalError: local variable 'score' referenced before assignment 我该如何解决这个问题？

Answer 1

如果分数仅在问题函数中引用，请尝试在函数开始时为其分配值 0。

如果您需要在函数外引用它，请尝试在函数外为其赋值并传入。

Answer 2

代码：

import time
def question(answer,correctanswer,score):
    print('question')
    print('A = ', answer[0])
    print('B = ', answer[1])
    print('C = ', answer[2])
    print('D = ', answer[3])
    answer = input('Remember, Case sensitive!\n')

    if not answer in ["A","B","C","D"]:
        print('Invalid, try again')
        question(answer,correctanswer,score)

    if answer == correctanswer:
        print('Correct! Score +1')
        score = score + 1
        print('Score = ', score)
    else:
        print('Incorrect! The glowing device in my arm buzzed. The world around me started to pixelate. I felt a sharp zap in my arm and everything went black')
        print('Score - 1')
        score = score - 1
        print('Score = ', score)
        print('░▒█▀▀█░█▀▀▄░█▀▄▀█░█▀▀░░░▄▀▀▄░▄░░░▄░█▀▀░█▀▀▄')
        time.sleep(0.5)
        print('░▒█░▄▄░█▄▄█░█░▀░█░█▀▀░░░█░░█░░█▄█░░█▀▀░█▄▄▀')
        time.sleep(0.5)
        print('░▒█▄▄▀░▀░░▀░▀░░▒▀░▀▀▀░░░░▀▀░░░░▀░░░▀▀▀░▀░▀▀')
        # question(nextanswer,nextcorrectanswer,score)

score = 0
question(["answer1","answer2","answer3","answer4"],"C",score)

结果：

question
A =  answer1
B =  answer2
C =  answer3
D =  answer4
Remember, Case sensitive!
A
Incorrect! The glowing device in my arm buzzed. The world around me started to pixelate. I felt a sharp zap in my arm and everything went black
Score - 1
Score =  -1
░▒█▀▀█░█▀▀▄░█▀▄▀█░█▀▀░░░▄▀▀▄░▄░░░▄░█▀▀░█▀▀▄
░▒█░▄▄░█▄▄█░█░▀░█░█▀▀░░░█░░█░░█▄█░░█▀▀░█▄▄▀
░▒█▄▄▀░▀░░▀░▀░░▒▀░▀▀▀░░░░▀▀░░░░▀░░░▀▀▀░▀░▀▀

question
A =  answer1
B =  answer2
C =  answer3
D =  answer4
Remember, Case sensitive!
C
Correct! Score +1
Score =  1

Answer 3

添加分数的函数

您可以在 question() 函数之外使用另一个名为 addscore() 的函数，它会为分数加分并打印出所有必要的信息。

def addscore(score, add=0, subtract=0):
    if add > 0:
        print(f'Correct! Score + {add}')
    elif subtract > 0:
        print('Incorrect! The glowing device in my arm buzzed. The world around me started to pixelate. I felt a sharp zap in my arm and everything went black')
        print(f'Score - {subtract}')
        
    score = score + add - subtract
    print('Score = ', score)
    
    if subtract > 0:
        death.start()
        print('░▒█▀▀█░█▀▀▄░█▀▄▀█░█▀▀░░░▄▀▀▄░▄░░░▄░█▀▀░█▀▀▄')
        time.sleep(0.5)
        print('░▒█░▄▄░█▄▄█░█░▀░█░█▀▀░░░█░░█░░█▄█░░█▀▀░█▄▄▀')
        time.sleep(0.5)
        print('░▒█▄▄▀░▀░░▀░▀░░▒▀░▀▀▀░░░░▀▀░░░░▀░░░▀▀▀░▀░▀▀')
        question()

    return score

实施

之后，就可以将这个功能实现到原来的question()功能中。有了这个，你可以加多一分。

例如
这将添加 5 个点并打印消息。

score = addscore(score, add=5)

或者这样减去3分。

score = addscore(score, subtract=3)

玩得开心！
