RegEx Code Challenge: Word Length... lengths are right, but getting "Bummer".

I'm using this code: 

import re

# EXAMPLE:
# >>> find_words(4, "dog, cat, baby, balloon, me")
# ['baby', 'balloon']

def find_words(count, sample):
    repeater = r'[A-Za-z]{'+str(count)+',}'
    return re.findall(repeater, sample)

which seems to return the correct list of words in the failure output.

Bummer! Didn't get the right output. Output was ['Treehouse', 'student', 'Kenneth', 'Python']. Length was 6.

What's gone wrong here?

Well, it's not returning the complete list that is expected.

Apparently they consider a "word" to be a string of alphanumeric characters (not strictly alphabetic).

Yeah, you're right. "Word characters" is the term used in the challenge. Changing the [A-Za-z] to simply \w passes, so the code is changed to pass as: 

def find_words(count, sample):
    repeater = r'\w{'+str(count)+',}'
    return re.findall(repeater, sample)
