This part I can understand but, as Steven has pointed out, this behaviour changes if the object being repeated is immutable. Why would one get a new object (rather than a new reference to it) just because it is immutable? It's this difference in behaviour that depends on mutability that I still don't understand even though Steven did try to explain it to me: """ If the list items are immutable, like ints or strings, the difference doesn't matter. You can't modify immutable objects in-place, so you never notice any difference between copying them or not.
