Sentiment analysis on Trump's tweets using Python by @FerroRodolfo via @ThePracticalDev

This tutorial shows how to use Twitter's API to access a user's Twitter history and perform basic sentiment analysis using Python's textblob package. Includes lots of code snippets and it's trivial to swap in any Twitter user you might be interested in.

This is just genius - you really need to read/understand and try this so that you can then use the same techniques/methods on other data.
