Github is the de facto home of open source software on the web. While there are other platforms that provide
similar (and in some cases better) services, it is still the place for some of the largest open source software
projects in the world. You will be creating an account on Github for several reasons:
1. we will be using Github to store, transmit and share homework and lecture notes,
2. we will use Github for at all assignments,
3. at some point in your future, you will very likely be using Github, if for private work for a company or
public work on an open source project.
§ Find ONE Github repository of interest and explore it. There is nothing to turn in for this task
– just begin to explore Github.
(25%) Work with exploring unstructured data with Python and text
In this part, you will explore some text data and get a little familiar with Python’s parsing and text capabilities.
You will grab data from the free books provided online from Project Gutenberg and use the provided code
to compare these documents. Turn in the answers to the given tasks after studying the code provided in
gutenberg_get_words() which takes a url for a book on Project Gutenberg and returns a list of the words
in the book. Notice the stopwords= parameter is used to eliminate words that relay low or no information.
This is a common technique use in text processing.
These five books will be used for the tasks for this question:

['london', 'i', 'walk', 'streets', 'petersburgh', 'i', 'feel', 'cold', 'northern', 'breeze', 'play', 'cheeks§ submit the Python code that does the following:
• using the code and the 5 books provided above, explore and apply the very nice Python library called
collections. Use the Counter class to load the word frequencies of each book into a Python dictionary.
• NOTE: you will need to be online with an internet connection for this to work, since it loads the data
directly from the URLs of the books.
§ turn in at least 2 sentences and any code if you used code to answering the following:
• there are similarities and differences in the top 30 words of the five provided documents – be specific
about describing what they are? How similar or different are each of the top 30 words list? You can
compare them by hand (look at them) or you are encouraged to write Python code to compare them
