Can anyone help with this (easy) RE problem?

It's quite straight forward, I just can't seem to get it right?! Thanks for any help.

word_length.py 
import re

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

def find_words(count, string):
    word_len = r'\w{len(count),}'
    return re.findall(word_len, string)

:point_right: When building your string, you need to include the count value.

You can do this by converting it to a string and concatenating it with the rest of the string. What you had before just included the word "count" (along with len()?) as part of the string.

    word_len = r'\w{' + str(count) + ',}'
