Trying to understand

Im trying to get my head round python and its going ok but i just wondered if i could ask a question about the walk script in the walkthrough template from blender3d.com

player = cont.getOwner()
speed = player.maxspeed
vec = [0, 0, 0]

if player.flymode:
	shoulder = cont.getActuator('shoulderipo').getOwner()
	playerOri = shoulder.getOrientation()

else:
	playerOri = player.getOrientation()

playerX = [playerOri[0][0], playerOri[1][0], playerOri[2][0]]
playerY = [playerOri[0][1], playerOri[1][1], playerOri[2][1]]

if fwdkey.isPositive():
	vec = VEC_add(vec, playerY)

Im just wondering what the second bracket is when defining playerOri for playerx and y. (eg [playerOri[0][1], etc) what does that 1 refer to? Is it to with getting local coords rather than global?

Thanks

its a list of lists… ie

cow=[ [ a ,b] , [c, d] ]
moo=cow[1]

so now moo==[c,d] and moo[1]==d

or just cow[1][1]==d

hope this helps… probably already got this answered in the python docs
