使用.isupper（）时遇到问题

Question

我的程序是密码强度模拟器，每当我输入密码时，总是输出得分为1。

def upper_case():
    points = int(0)
    limit = 3
    for each in pword:
        if each.isupper():
            points = points + 1
        if points > limit:
            points = limit
        else:
            points = points + 0
        return points

pword = raw_input("ENTER: ")
upper_case()

points = 0
points += upper_case()

print points

Answer 1

您过早地返回points，因为您将它缩进太远了。删除缩进：

def upper_case():
    points = int(0)
    limit = 3
    for each in pword:
        if each.isupper():
            points = points + 1
        if points > limit:
            points = limit
        else:
            points = points + 0
    return points

您可以将其简化为：

def upper_case(pword):
    return min((sum(1 for each in pword if each.isupper()), 3))

我将函数更改为参数而不是使用全局。
