[Tutor] Duplicating lists in variables?

But of course!  You could use the copy module, which can copy 
anything.  But there's a sneaky way to use the slice operator which 
is more common:

bar = foo[:]

This works because the slice operator returns a new list which is a 
subset of the original.  But if the subset starts at the beginning, 
and continues till the end, then it happens to be a copy of the 
entire list!
