tsaylor / countdown.py

Last active August 29, 2015 14:12

An example of threaded python code. Starts with a number of seconds entered by the user, then spawns a thread to countdown those seconds and another to prompt the user to add more seconds to the clock. Demonstrates one thread manipulating another.

	(i, seconds) = (0, 5)


	def countdown():
	global seconds, i
	while i < seconds:
	time.sleep(1)

tsaylor / matcher.py

Created April 23, 2011 02:08

This is a tool for measuring the similarity between two lists. The more items that are the same or ranked near each other, the higher the score. I believe I used this to determine the best match for rankings of some items, but I have no idea now.

	import random, math

	position_weighting = 3.0
	max_pos = 10
	near_miss_scaling = 1.0 # bigger means higher scores


	total_points = 0
	total_match_points = 0
	sf=[]
