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, -Hans -- http://mail.python.org/mailman/listinfo/python-list
