Question 1: Importing the Data

The data for this assignment was obtained using the Twitter APIs (https://developer.twitter.com/en/docs/twitter-api). To ensure that everyone has the same data and to eliminate the need for every student to apply for a Twitter developer account, we have collected a sample of tweets from several high-profile public figures. The data is stored in the folder data . Run the following cell to list the contents of the directory:

In [3]:

AOC_recent_tweets.txt

BernieSanders_recent_tweets.txt BillGates_recent_tweets.txt

Cristiano_recent_tweets.txt

EmmanuelMacron_recent_tweets.txt elonmusk_recent_tweets.txt

Question 1a

Let's examine the contents of one of these files. Using the open function (https://docs.python.org/3/library/functions.html#open) and read operation (https://docs.python.org/3/tutorial/inputoutput.html#methods-of-file-objects) on a python file object, read the first 1000 characters in data/BernieSanders_recent_tweets.txt and store your result in the variable q1a . Then display the result so you can read it.

Caution: Viewing the contents of large files in a Jupyter notebook could crash your browser. Be careful not to print the entire contents of the file.

 

Hint: You might want to try to use with :

 

with open("filename", "r") as f: f.read(2)
