When using inventory[:] instead of inventory.copy() same result is obtained. Why?

i tried using inventory[:] or inventory[0:] while removing all the elements of the list and the result obtained is [] similar to that of inventory.copy() even though python is not creating another object. So why is the giving the exact same result?

A slice does create another object, and one with no arguments does exactly the same thing as the "copy" method.
