"multi" zip

[Mark]

So,

Let line be a list of lists where the sublists are the same length.

For example:

line = [ [0,1,2], [3,4,5], [6,7,8] ]

Now, I can do:

zip(line[0], line[1], line[2])

to "invert" the array.  Now, I'd like to do two different things:

1) instead of producing tuples, I'd like to produce lists.

2) I'd like to extend this to an arbitrary number of lists.  If it were 
possible, I'd do zip(line[0], line[1], ..., line[n]) but this doesn't seem 
to compile :).

Is there a way to make zip() do this, or should I stop trying to hammer with 
a wrench?
