Editing Community Data Science Course (Spring 2016)/Day 4 Coding Challenges

Each of the challenges this week will ask you to modify and work with code in the [[Community Data Science Course (Spring 2015)/Wikipedia API projects|Wikipedia API projects]] which you should have installed and begun working with in class.

As always, it's not essential that you solve or get through all of these — I'm not grading your answers on these. That said, being able to work through at least many of them is a good sign that you have mastered the concepts for the week. It is always fine to collaborate or work together on these problem sets. The only thing I ask is that you do not broadcast answers before Sunday at midnight on Canvas.

== Challenges ==

# Save the revision metadata printed in <code>wikipedia1-2.py</code>  (i.e., the material already being printed out) to a file called "wikipedia_revisions.tsv".
# Print out the revision ids and edit summaries (i.e., <code>comment</code>) of each revision for the article on Python.
# Find out what other data or metadata you can print out for a revision for an article.
# Which article is in more categories? [[:wiki:Python (programming language)|Python (programming language)]] or [[:wiki:R (programming language)|R (programming language)]]?  
# Find out how many revisions to the article on "Python (programming language)" were made by user "Peterl"? How about "Hfastedge"?
# How would you use the API to find out how many revisions/edits the user "Benjamin Mako Hill" has made to Wikipedia?
# Can you build a list of all of the articles edited by "Benjamin Mako Hill"? What is the article with the longest title that user Benjamin Mako Hill has edited?
# How many edits to the article "Python (programming language)" where made in 2014?

;Here's a much more complicated challenge but a fun one that you know enough to solve: Check out the game [http://kevan.org/catfishing.php Catfishing] which shows you categories and has you guess an article. Write a version that uses the Wikipedia API. For example, pick 5 articles and write a program that will randomly show the categories for one of those articles and to ask you to guess the article. Read the guess with <code>input()</code> and let the user know if they go it right or wrong!
