Duplicating a variable

I have run into a bit of a subtle problem. How do I go about
duplicating a variable (particularly a list of lists) in python. I
was surprised when simple assignment didn't work. For example, let y =
[1,2,3]
>>> x = y
>>> x[2] = 5
>>> y
[1,2,5]
It seems that simply assigning x to y allows further modification of y
via x. (I'm new to python and I'm sure this is obvious to experienced
users). So my question, how do I go about duplicating a variable
which I can then manipulate independently?
Thanks,
