为什么我的for循环不检查每个字符？

Question

所以我是python的初学者,我不能为我的生活弄清楚为什么它不会检查并添加每个字母

def howstrong (password):
    points = len(password)
    charactersallowed = ["!", "$", "%", "^", "&", "*", "(", ")", "-", "_", "=", "+"]

    for ch in password:
        if ch.isupper():
            points= points+5
        elif ch.islower():
            points = points+5
        elif ch.isdigit():
            points = points+5
        elif ch in charactersallowed:
            points= points+5
        else:
            points = points+0
        return points

如果输入密码密码!在我的代码中它告诉我我的积分是14但是这个密码应该是24？下面我将添加我的其余代码,但我怀疑它在那部分,我相信我的for循环中有一个错误.

def checkingmain():

    while 1:
        p = input("\nEnter password: ")
        if len(p) < 8 or len(p) > 24:
            print("Password must be 6 to 12 characters.")
        elif input("Re-enter password: ") != p:
            print("Passwords did not match. Please try again.")

        else:
            score= howstrong(p)
            if not score:
                print("Invalid character detected. Please try again.")

            else:
                if score <= 0:
                    print("your password is weak",score)
                elif score>0 and score<20:
                    print("your password is medium",score)
                else:
                    print("your password is strong",score)
            break

我很感激,如果有人能用一个有点蟒蛇初学者的可理解的解决方案回复我.

它只检查第一个字符,因为你返回循环内部.将return语句移回一个缩进,因此它不在for循环中.
