Python Regular Expressions in Python Introduction to Regular Expressions Word Length

Regular expressions

I don't get it, I turned it to a string because I got a TypeError (TypeError: can only concatenate str (not "int") to str). It's still not working.

import re

# >>> find_words(4, "dog, cat, baby, balloon, me")
# ['baby', 'balloon']
def find_words(count, string):
    return re.findall(r'\w{' + str(count) + '}', string)

note: I tried it on Pycharm and it worked.

You are SO close. You are finding words of exactly count characters long, not “count or greater”. A missing comma will solve it.

Post back if you need more help. Good luck!!!

lmao. Thank you so much, I should start reading questions carefully. That's what I lack.
