Not sure why this isn’t working

I can’t tell what I’m missing here that’s not making it work

import re

# >>> find_words(4, "dog, cat, baby, balloon, me")
# ['baby', 'balloon']
def find_words(count, string):
    return re.findall(r'\w{count,}\b', string)

You have the right idea, but currently the word "count" is part of the literal regex string. But what you probably want is to have the value that the variable represents as part of the regex instead.

You can fix it with a little formatting or concatenation.
