regular expressions - word length question

Hi there,

I am currently using this code to try to solve the challenge, but only receiving an empty list as output:

def find_words(count, str1):

    return re.findall(r"\w{%d, }" % count, str1)

If I change %d to either %s or %r, it does not seem to work either. Would someone be so kind as to explain to me what I am missing?

Thanks!

[MOD: added ```python wrapper for formatting. -cf]

All character that goes into regular expression are sensitive, all of them have meaning. With that in mind {%d, } does not work because of extra space character you added. So remove the space character.
