Python In Lunix

[nilamo]

Start with something simple, that you can test over and over, like maybe this:

import re

regex = re.compile(r"your-regex-here")

test_strings = [
  "Jose",
  "Jjunior",
  "4chr",
  "letters",
  "ending-in-number5",
  "athenbthenc",
  "Capital",
  "doesn'tmatch@nyth1ng"
]

I'd suggest using something like regexpal (http://www.regexpal.com/) to test out your regex quickly to find something that works for each case.
But really, there's almost no python involved here... it's all just regular expressions.
