Question

I am trying to make a password strength tester. The password needs to have at least 4 numbers and 6 letters, so I need to find out how many of each were entered by the user in raw_input.

Answer 1

Just iterate over the password:

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
