How to print a key from json object : I have following code which is used to get news articles from google news:

    import newsapi
    import requests
    
    from newsapi.articles import Articles
    
    a = Articles(API_KEY="myapikeyforthisservice")
    
    res= a.get_by_top(source='google-news')
    
    results= res['articles']
    
    print(results)

It returns me results in JSON with following entries for all articles are displayed.

    "author": "Rachel Kaser",
    "title": "AOL Instant Messenger to shut down after 20 years",
    "description": "AOL announced that its iconic chat service from the '00s is officially going dark after 20 years -- and we're sad to see it go.",
    "url": "https://thenextweb.com/socialmedia/2017/10/06/aol-instant-messenger-shut-down/",
    "urlToImage": "https://cdn0.tnwcdn.com/wp-content/blogs.dir/1/files/2017/10/AIM-social.jpg",
    "publishedAt": "2017-10-06T16:13:02Z" 

What I want to do is to get only `title` and `description`not all the entries.I don't know how to do it. 
I tried `results=res['articles'['description']]` which gave me error "" *list indices must be int or slice, str given*

and `results=res['articles'[2]]` which returns above mentioned results for 3rd article in the list.

Both did not work for me.

Can anybody tell me how to do it? Any help will be appreciated.
