I keep getting a None group error. Anyone else have this issue?

I've tried adding a group in, but it just says Try Again!

import re

def first_number (String):
    result.group(1) = re.search(r'\d', String)

The challenge requires that you search for the 1st number and return the match object. Rather than printing the result of the search , you should return the result of the search like this;

def first_number (String):
    result = re.search(r'\d', String)
    return result

or if you wanted to simplify, you can also this

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

If a match is not found the returned value will be None
