Hi, there

Could you please help me to clarify what is wrong with my code

import re

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

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

You can't do string formatting when doing regular expressions. You'll need to find another way to join the count and regex pattern together.

This is my code:

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

I think I can find the exact match of count long but I can't do the longer count? Is there anybody help me?
