Quick Check: Python del Statements

Review

1. What happens when `del name` deletes a bound name?

   Deleting a name removes that binding; the object can still have other references.
2. What does `del letters[1]` do to a normal list?

   An indexed deletion removes that list item and the later items shift left.
3. Which target removes a range from a list?

   A slice target in a del statement removes that range from a mutable sequence such as a list.
4. After `alias = items; del items`, what can still be true?

   Deleting one binding does not remove another binding to the same object.
5. What exception does deleting an unbound name raise?

   The official language reference specifies NameError for deleting an unbound name.
