Finding optimal rational approximations of pi

I've got a beef with Pi "Approximation" Day

March 14 (3.14), often known as Pi Day, is a cute idea. I mean, June 28 would certainly be better, but that's not what this is about.

The chip on my shoulder is the shaft that July 22 (22/7) gets. Pi Approximation Day.

It's an apt description, but it has an odd implication. If 22/7 is a pi approximation, then I guess 3.14 = 157/50 = pi? Yeah okay.

NYLT Scoutmasters' Minute

That was great, wasn't it? I love campfires. There's just something aobut flame that kind of gets you to thinking.

It can be a campfire, or a candle, a lantern... the flame dancing in the air just draws you in, and can make you think.

So what is a flame? It's something we learn very early in our Scouting career. What are the three ingredients for a flame? (ask for help)

Heat, air, and fuel. Without just one of these, the flame cannot survive. If you lack heat, your flame will just go out. Without air, your flame will choke and be snuffed out. Without fuel, your flame will starve and die away.

I keep talking about how I've been here working for this camp for almost a decade. It's important for you all to know why we're doing this. We aren't paid; in fact, we're each paying to be here, giving up our gas, a week of our paychecks, our time lounging by the pool or playing video games or whatever else we'd otherwise be doing.

All of the tools I use in my work are open-source: this typically means that

# Ask user for text file to inspect
filename = raw_input('Enter name of text file to inspect: ')
# If the file is legit
# Grab file
f = open(filename)
# Read file, make all lowercase
file_string =
# Remove all non word characters
