Why would you want to [deep]copy a slice object? Anyway, I don't know much about them, other than that they are slightly unusual objects that play a very restricted role in python, rather like the Ellipsis. Workarounds are possible, I think, but really you almost certainly don't need to do this. Peace, ~Simon -- http://mail.python.org/mailman/listinfo/python-list
