How to take output from iterating, store that in a dictionary
<p>So I have this script (running Python 3.5) using Google API and Newspaper.  It searches google for articles that have to do with sleep. And then using Newspaper, I iterate over those URLS. And all I'm asking Newspaper to do is return a list of keywords of that article, which I call by writing <code>article.keywords</code> .</p>

<pre><code>for url in google.search('sleep', num=2, stop=1):
    article = Article(url)      
    article.download() 
    article.parse()
    article.nlp()     
    print(article.keywords)
</code></pre>

<p>The keywords that are returned (for a given article) look like this:</p>

<pre><code>['education', 'nights', 'start', 'pill', 'supplement', 'research', 'national', 'sleep', 'sleeping', 'trouble', 'using', 'taking']
</code></pre>

<p><strong>But I want to create a dictionary full of ALL of the keywords for all the results: That is, the keywords for each article that is being iterated over. How would I do that?</strong> </p>
