Every week, I attempt to solve the NPR Sunday puzzle with Python. Generally speaking, I only allow myself to use

• Only core Python libraries and NLTK
• The Wikipedia API
• FamousNames.txt (also culled from Wikipedia)

It's impressive what you can do with these tools -- get rhyming words, lists of category members, all sorts of wordplay operations. Hopefully you'll like looking through the examples as much as I liked making them. Enjoy!
