Yea, I got that part.

That's what I thought, but the OP seems convinced that c[:] is
somehow behaviorally different than c (something more than just
being an exact copy of the list with a different id()).
The only thing I could think of is that he has overridden the
__getitem__ method of the class to which c belongs with
something that has some sort of side-effects which he wishes to
invoke.

He could just define a container class that does what he
wants...
