How do I input the count given into the line re.findall(r' so that it references the number given?

Thanks in advance

word_length.py 
import re

def find_words(int,str):
    re.findall(r'
# EXAMPLE:
# >>> find_words(4, "dog, cat, baby, balloon, me")
# ['baby', 'balloon']

A recurrence constraint in a regex is created with one or two numbers, and perhaps a comma, within curly braces ({}).

For more details, see the re syntax section in the Python reference guide.
