Are strings even compatible with re.match?

I know Kenneth showed how to open and read a file, but can you do the same with a string?

escapes.py 
import re

def first_number(string):
  return re.match('\d', string)

Yep. re.match() just wants a string to match against. If you remember, when we were using it to search a file, we were really searching a string we made from the file.

The only Escape hatch that matches this is \w, but it matches 'a' instead because the number isn't the first character.
