using variables for matching

It appears I cannot use variables as params for matching, as shown below. Is there a way to do r'\w{var,}' to bring back words of var or more characters long? also, is the result of re.findall() a list?

word_length.py 
import re

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

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

find_words(count, string)

Think all the way back to Python Basics. How do you add two or more strings together?
