newbie : array initialization, anyone ?

[Gerson Kurz]

you can initialize a fixed-size array using something like

	array = [0] * 10

now, one would think that you can initialize a multidimensional array
like this:

	multidim = [ [0] * 10 ] * 3

but now, all 3 elements in multidim are references to the same single
array, so that if you type

	multidim[0][0] = 1
	print multidim 

you actually get three 1 in all those 0s. Where did my thinking go
wrong along these lines ?
