Didn't get the right output. I'm stumped.

I'm getting the error above, however, I am not sure how to fix it.

word_length.py 
import re

def find_words(count, str1):
  words = re.findall(r'\w{count,}', str1)
  return words

Remember that things in regex patterns aren't interpreted. That count you have in there is literally the letters 'c', 'o', 'u', 'n', and 't'. You need to get the count variable into your string to use it. Since .format() is weird with regular expressions (since {} are meaningful characters in regex), I'd recommend using string concatenation.

The system is telling me that count is of type int?

Yes, count is an integer. How do you turn a number into a string?

Holy crap I made that WAY too hard on myself. Now I feel semi-belittled by a damn computer.

Thank you, Kenneth
