Python 在何处定义使用函数的变量

无法打印“问题”函数中定义的“分数”变量。 令人不安的代码：

def question(attempt, answer):
    score = 0
        #if attempt is true, add 1 to score
        #if attempt is false, do nothing to score
    if attempt == answer:
        score += 1

print("How many ducks are there?")
question(input(), "14")

print("Your score is %r." % score)

虽然，当我尝试运行它时，我得到的是：

Traceback (most recent call last):
  File "quiz.py", line 11, in <module>
    print("Your score is %r." % score)
NameError: name 'score' is not defined

回溯（最近一次呼叫最后一次）：
文件“quick.py”，第11行，在
打印（“您的分数为%r.%score）
NameError:未定义名称“分数”

如果您能帮助您找出变量的位置，我们将不胜感激。

您必须缩进函数中运行的代码，还必须从函数中返回一些值

def question(attempt, answer):
    score = 0
    #if attempt is true, add 1 to score
    #if attempt is false, do nothing to score
    if attempt == answer:
        score = 1
    return score

您应该计算函数之外的全局分数，即

score+=问题（尝试，回答）

我会在函数中打印它，函数返回：

>>> print("How many ducks are there?")
How many ducks are there?
>>> question(input(), "14")

Your score is 0.
