问题描述
我正在尝试制作一个密码强度模拟器,它要求用户输入密码,然后返回分数.
I am trying to make a password strength simulator which asks the user for a password and then gives back a score.
我正在使用:
islanum()
isdigit()
isupper()
试试看输入的密码有多好.
to try and see how good the inputted password is.
我希望它不是返回布尔值,而是评估密码的每个字符,然后程序将所有真"值相加并将其转换为分数.示例代码:
Instead of returning boolean values, I want this to assess each characters of the password, and then the program to add up all the "True" values and turn it into a score. EXAMPLE CODE:
def upper_case():
points = int(0)
limit = 3
for each in pword:
if each.isupper():
points = points + 1
return points
else:
return 0
任何帮助将不胜感激!谢谢!!
Any help would be much appreciated!! THANKS!!
推荐答案
.isalnum()
, .isupper()
, .isdigit()
和朋友是 Python 中 str
类型的方法,调用方式如下:
.isalnum()
, .isupper()
, .isdigit()
and friends are methods of the str
type in Python and are called like this:
>>> s = "aBc123"
>>> s[0].isalnum()
True
>>> s[1].isupper()
True
>>> s[3].isdigit()
True
简单的getscore()
功能:
Simple getscore()
Function:
s = "aBc123@!xY"
def getscore(s):
score = 0
for c in s:
if c.isupper():
score += 2
elif c.isdigit():
score += 2
elif c.isalpha():
score += 1
else:
score += 3
return score
print getscore(s)
输出:
13
更好的版本:
s = "aBc123@!xY"
def getscore(s):
return len(s) + len([c for c in s if c.isdigit() or c.isupper() or not c.isalpha()])
print getscore(s)
输出:
17
