Regex: find_words challenge. What am I missing?


import re

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

def find_words(count, string):

You're got the right idea, but you don't want the literal word "count" in your RegEx expression.

Instead, use a mechanism like concatenation, the "format" function, or an "f-string" to include the value of the "count" variable in the expression.

Once you fix that you should pass the challenge.
