Exercise

Character count of Russian tweets

In this exercise, you have been given a dataframe tweets which contains some tweets associated with Russia's Internet Research Agency and compiled by FiveThirtyEight.

Your task is to create a new feature 'char_count' in tweets which computes the number of characters for each tweet. Also, compute the average length of each tweet. The tweets are available in the content feature of tweets.

Be aware that this is real data from Twitter and as such there is always a risk that it may contain profanity or other offensive content (in this exercise, and any following exercises that also use real Twitter data).
