It will delete the *name* `item`. It does nothing to the object that was
bound to that name. If the name was the only reference to that object, it
may be garbage collected sooner or later. Read the documentation for the
`__del__()` method for more details and why implementing such a method
increases the chance that the object *won't* be garbage collected!
Relying on the `__del__()` method isn't a good idea because there are no
really hard guaranties by the language if and when it will be called.
