Python Regular Expressions in Python Introduction to Regular Expressions Word Length

Posted by Adiv Abramson

The challenge raised an error: "Didn't get the right output. Got 4 items. Should have gotten 4." ???

I tested my code in IDLE. It yields the same results when fed the sample data provided in the comments. It also accurately processes different inputs. I am not sure what's wrong with my code. Any hints or suggestions on how to make it work right would be greatly appreciated.

word_length.py 
import re

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

def find_words(count, words):
    matches = []
    word_list = words.split(',')
    for each_word in word_list:
        if len(each_word.strip()) >= count:
            matches.append(each_word)

    return matches

I've made that error message a bit more explicit. You need to be using re.findall() and not just splitting the string on commas.

I'm guessing because you didn't use regular expression to complete the challenge and it probably checks for that.
