如何在python中插入分数计数器

Question

def quiz(demand,correct):
    print(" ")
    Score=0
    Answer=input(demand)
    Answer=Answer.lower()
    if Answer!="y" and Answer!="n":
        print("I did not understand the answer")
        quiz(demand,correct)
    elif Answer==correct:
        print("correct answer")
        Score=Score+1
        return Score
    else:
        print("wrong answer")
demand1="the Napoleon's horse is white? y/n: "
correct1="y"
quiz(demand1,correct1)
demand2="berlusconi is president of italy? y/n: "
correct2="n"
quiz(demand2,correct2)
print("score:",Score)

我试图插入分数计数器，  为什么不起作用？  有人可以给我解决方案吗？  抱歉我的英语不好。

Answer 1

问题是范围，每次拨打score时quiz都会设为零 最快的解决方案如下

Score=0
def quiz(demand,correct):
    print(" ")
<everything else is the same>

Answer 2

调用该函数并将值赋给变量并打印。请注意，变量范围是函数的本地范围，从外部调用它需要一些特殊的声明global。

Score = 0
def quiz(demand,correct):
    global Score
