Right now your passing a string to findall that includes the word count. What you want to do is convert the number that count represents to a string and then insert that into the string that you pass to find all. Break the string you pass to findall into two parts, before count and after count. Convert the value of count using the str() function and add it into the string for findall.

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