word_length challenge

i understand the question that is being asked, i just dont get why my code isnt passing. im making an empty list that will hold all the words in my string that a longer or have the same amount of characters as "int". then im going through the string checking for words longer than {int}. and then appending those words that fit the description. any help would be awesome. thanks

word_length.py 
import re

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

def find_words(int, str):
  words = []
  search = re.findall(r'\w{int}', str)
  words.append(search)
  return words

Remember, regex are dumb so '\w{int}' literally says "look for an 'int' number of word characters". What number is 'int'? Not the variable int, literally the characters 'int'. You'll have to get your variable value into the string somehow. I'd suggest concatenation.
