Finding keywords
Counting known keywords is one of the first ways you can analyze text data in a Twitter dataset. In this dataset, you're going to count the number of times specific hashtags occur in a collection of tweets about data science. To this end, you're going to use the string methods in the pandas Series object to do this.
pandas and numpy have been imported as pd and np, respectively. A more fully-featured flatten_tweets and data_science_json have also been loaded for you.
