title: Setting n-grams for sentiment analysis with Python and TextBlob
body: <p>I want to do sentiment analysis of some sentences with <code>Python</code> and <code>TextBlob</code> lib.
  I know how to use that,  but Is there any way to set <code>n-grams</code> to that?
  Basically, I do not want to analyze word by word, but I want to analyze 2 words, 3 words, because phrases can carry much more meaning and sentiment.</p>
  
  <p>For example, this is what I have done (it works):</p>
  
  <pre><code>from textblob import TextBlob
  
  my_string = "This product is very good, you should try it"
  
  my_string = TextBlob(my_string)
  
  sentiment = my_string.sentiment.polarity
  subjectivity = my_string.sentiment.subjectivity
  
  print(sentiment)
  print(subjectivity)
  </code></pre>
  
  <p>But how can I apply, for example n-grams = 2, n-grams = 3 etc?
  Is it possible to do that with <code>TextBlob</code>, or <code>VaderSentiment</code> lib?</p>
