these questions I’m super confused with, if u can helpme with the option, if u could tell me the correct option withreasoning that would be great. thank you!
Given the code below, which of the following statements could go in the main block and would execute without raising an error? class Mystery: *”A mystery class without any implementation. pass if main name None of the above. They would all raise an error. m- Mystery() print (m) m- Mystery() m- Mystery(‘what is this?’) Which of the following is true about abstract classes? Abstract classes should never be instantiated It is acceptable to instantiate an abstract class in any situation Abstract classes should only be instantiated when a more specific subclass does not exist An abstract class can be instantiated if it is likely that the abstract methods will never be called Suppose we have a Parent class that has a method that is not completed because child classes have different implementations. Fill in the blank in the code below. class Parent: # docstring, def method(self) -> None: init omitted A method that differs for each of the child classes. raise self spring A library contains books and DVDS, which can be checked out and returned. A warning is sent to borrowers who have overdue items. Books can be renewed but DVDS cannot, and DVDS have a shorter loan period than books. The library may expand in future to include other kinds of items. Suppose you are designing classes for the library. Which of the designs below is most appropriate? A Book class and a DVD class that have no relationship A Libraryltem class whose attributes can be initialized differently depending on whether it represents a book or DVD A Book class and a DVD class that are unrelated, and a Libraryltem class that stores an instance of Book or DVD in an instance attribute A Libraryltem parent class that stores common information such as due date, and child classes Book and DVD.
