Exercise

Stems from tweets

In this exercise, you will work with an array called tweets. It contains the text of the airline sentiment data collected from Twitter.

Your task is to work with this array and transform it into a list of tokens using list comprehension. After that, iterate over the list of tokens and create a stem out of each token. Remember that list comprehensions are a one-line alternative to for loops.
