Another solution for this challenge on re.findall() ?

I found a solution, but it does not seem to be the best. Do you have a better solution for this challenge ? The objective is to find all words in a given string of length "count" or more.

import re

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

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

Your solution is fine. There are other string formatting you can use but there are nearly equivalent.

Other forms:

    return re.findall(r'\w{' + str(count) + ',}', string)

    return re.findall(r'\w{%s,}' % count,string)

    return re.findall(r'\w{{{0},}}'.format(count), string)
