Looking at various Python implementations of Conway's game of life. I came across one on rosetta using defaultdict.
http://rosettacode.org/wiki/Conway%27s_Game_of_Life#Python Just looking for your opinion on style would you write it like this continually calling range or would you use enumerate instead, or neither (something far better) ? import random from collections import defaultdict printdead, printlive = '-#' maxgenerations = 3 cellcount = 3,3 celltable = defaultdict(int, { (1, 2): 1, (1, 3): 1, (0, 3): 1, } ) # Only need to populate with the keys leading to life ## ## Start States ## # blinker u = universe = defaultdict(int) u[(1,0)], u[(1,1)], u[(1,2)] = 1,1,1 for i in range(maxgenerations): print "\nGeneration %3i:" % ( i, ) for row in range(cellcount[1]): print " ", ''.join(str(universe[(row,col)]) for col in range(cellcount[0])).replace( '0', printdead).replace('1', printlive) nextgeneration = defaultdict(int) for row in range(cellcount[1]): for col in range(cellcount[0]): nextgeneration[(row,col)] = celltable[ ( universe[(row,col)], -universe[(row,col)] + sum(universe[(r,c)] for r in range(row-1,row+2) for c in range(col-1, col+2) ) ) ] universe = nextgeneration Just finished watching ned batchelders talk and wondering how far I should take his advice. http://nedbatchelder.com/text/iter.html Thanks Sayth -- https://mail.python.org/mailman/listinfo/python-list
