python - 我怎样才能让我的程序返回密码强度

Question

我正在努力使用我的密码评估程序。我怎样才能确保当我输入密码时，我的程序返回密码强度。当我运行这个程序时，它说 password_strength 存储在 .....) 是我在程序结束时调用的返回错误吗？

print ("Welcome to this password rater program")
print ("Your password needs to have a minimum of 6 characters with a maximum of 20 characters.")
print ("Your password can contain lowercase and uppercase characters, numbers and special characters")
print("")


password = input("Please insert your password: ")


def check_len(password):
    l = len(password)
    if 6 < l < 20:
        x = check_char(password, l)
    else:
        x =  0
    return x


def check_char(password, l):
    for i in range(l):
        ascii = ord(password[i])
        num = 0                                
        upper = 0                               
        symbols = 0
        lower = 0
        space = 0

        if  96 < ascii < 123:      
            lower = 15
        elif 47 < ascii < 58:     
            num = 25
        elif 64 < ascii < 91:     
            upper = 25
        elif ascii == 32:
            space = 30
        else:                               
            symbols = 25
        total = ((lower + num + upper + space + symbols) * len(password))
    return total


def password_strength(total):
    if total >= 1000:
        print("Your chosen password is Very strong")
    elif 700 < total < 999:
        print("Your chosen password is strong")
    elif 500 < total < 699:
        print("your chosen password is medium")
    elif total <= 500:
        print("Your chosen password is weak")
    return total


strength = check_len(password)
print(password_strength(strength))

Answer 1

首先，您告诉 python 打印函数，而不是函数的求值。这就是您收到该消息的原因。

此外，您永远不会调用您编写的任何函数。获得一个工作程序所有定义声明后如下:

调用 check_len 定义:

strength = check_len(password)

虽然这个定义不返回任何值。您可以将其更改为:

def check_len(password):
    l = len(password)
    if 6 < l < 16:
        x = check_char(password, l)
    else:
        x =  0
    return x

让它返回分数/强度。

最后，您应该使用“password_strength”定义来处理分数:

password_strength(strength)

这一行不需要打印，因为打印语句在定义本身。但是，如果您还想打印最终分数，可以将其放入以下行:

 print(password_strength(strength))

还有一个调试问题:您的 check_char 定义不带任何参数。您可以通过将其更改为:

def check_char(password, l):

最终代码: 打印(“欢迎使用此密码评估程序”) print ("您的密码需要最少 6 个字符，最多 16 个字符。") print("您的密码可以包含大小写字符、数字和特殊字符") 打印(“”)

password = raw_input("Please insert your password: ")


def check_len(password):
    l = len(password)
    if 6 < l < 16:
        x = check_char(password, l)
    else:
        x =  0
    return x


def check_char(password, l):
    for i in range(l):
        ascii = ord(password[i])
        num = 0                                
        upper = 0                               
        symbols = 0
        lower = 0
        space = 0

        if  96 < ascii < 123:      
            lower = 15
        elif 47 < ascii < 58:     
            num = 25
        elif 64 < ascii < 91:     
            upper = 25
        elif ascii == 32:
            space = 30
        else:                               
            symbols = 25
        total = ((lower + num + upper + space + symbols) * len(password))
    return total


def password_strength(total):
    if total >= 1000:
        print("Your chosen password is Very strong")
    elif 700 < total < 999:
        print("Your chosen password is strong")
    elif 500 < total < 699:
        print("your chosen password is medium")
    elif total <= 500:
        print("Your chosen password is weak")
    return total


strength = check_len(password)
print(password_strength(strength))     `
