python - raw_input 中的字母和数字计数

Question

我正在尝试制作密码强度测试仪。密码需要至少有 4 个数字和 6 个字母，所以我需要找出每个用户在raw_input.

Answer 1

text = "helloworld42"

numbers = sum(c.isdigit() for c in text)
letters = sum(c.isalpha() for c in text)

Answer 2

只需遍历密码：

import string

numbers = 0
letters = 0

for letter in raw_input('Enter a password: '):
  if letter in string.ascii_letters:
    letters += 1
  elif letter in string.digits:
    numbers += 1

print numbers, letters
