Making good single-elimination tourney brackets based on seeds. Optimally orders the bracket so that worse seeds get knocked out first by people as close as possible to their skill level.
def tourney_in_order(k):
"""
Tells you the bracket for a tourney with n=2^k competitors 1-n, where 1
is the best. The bracket is such that competitors lose in the order of
their skill to the person with a level of skill as close to theirs as
possible.
>>> bracket = tourney_in_order(4)
>>> print bracket

This python script gets all of your youtube viewing history into a convenient text file.
#---------------------------------------------------------------#
# This script manually goes through youtube and collects all #
# of your viewing history into a convenient text file. This #
# might take about 30min to an hour, depending on your #
# computer's RAM, processing speed, and internet connection. #
# Note that this program requires the splinter module to work. #
# Run 'pip install splinter' to get it. #

A very simple example showing you how to make more or less nice plots in python
from __future__ import division, print_function # Always do this just to
# ensure compatability
# between python 2.7 and 3
import matplotlib.pylab as P
# Always do these next to lines to enable LaTeX to be used on the
# matplotlib plots
