Printing split data in function
<p>I'm trying to test to see if my function is working properly but every time I run it, it returns nothing. Here is my code:</p>

<pre><code>def read_words(user_words):

    user_input_of_words = 'DOG CAT BIRD FISH'   
    words = user_input_of_words.split()

    print read_words(user_input_of_words)
    return words
</code></pre>

<p>Any help would be appreciated!</p>
