NoneType

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

I get this error:

Bummer! 'NoneType' object has no attribute 'group'. How should I fix?

escapes.py 
import re
def first_number(string):
    return re.match(r'\d',string)

Mona, good start, just just need re.search() instead of re.match():

import re

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

def numbers(count, string):
  return re.search(r"\d" * count, string)
