The __________ programming practice is centered on creating functions that are separate from the data that they work on.
procedural
An object is a(n)
instance
The practice of procedural programming is centered on the creation of objects.
False
In one approach to identifying the classes in a problem, the programmer identifies the ___________ in a description of the problem domain.
nouns
The _____________ method is automatically called when an object is created.
_ _init_ _
It is a common practice in object-oriented programming to make all of a class's data attributes accessible to statements outside the class.
False
A(n) ____________ is a component of a class that references data
data attribute
If a class has a method named _ _str_ _, which of these is a way to call the method?
by passing an instance of the class to the built in str function
A class method does not have to have a self parameter
False
Object reusability has been a factor in the increased use of object-oriented programming.
True
Starting an attribute name with two underscores will hide the attribute from code outside the class.TrueA set of standard diagrams for graphically depicting object-oriented systems is provided by .the Unified Modeling LanguageBy doing this, you can hide a class's attribute from code outside the class.begin the attribute's name with two underscoresWhy should an object's data attributes be hidden from code outside the class?It prevents accidental corruptionSuppose my_car is the name of a variable that references an object, and go is the name of a method. Write a statement that uses the my_car variable to call the go method. (You do not have to pass any arguments to the go method.)my_car.go()One way to find the classes needed for an object-oriented program is to identify all of the verbs in a description of the problem domain.FalseA(n) ____________ method stores a value in a data attribute or changes its value in some other way.mutatorYou cannot directly call the _ _str_ _ methodTrueWhen the _ _init_ _ method executes, what does the self parameter reference?It references the object that the method is to operate onA(n) ___________ method gets the value of a data attribute but does not change itaccessorWhat is encapsulation?Encapsulation refers to the combining of data and code into a single object.What is the difference between a class and an instance of a class?A class is a 'blueprint' that can be used to create objects. An instance of a class is an object of the data type that exists in memory.In one approach to identifying a class's data attributes and methods, the programmer identifies the class's .ResponsibilitiesThe ___________ programming practice is centered on creating objects.object-orientedWhat does a subclass inherit from its superclass?the subclass inherits everything from its superclass/ The superclass's attributes and methods.This characteristic of object-oriented programming allows the correct version of an overridden method to be called when an instance of a subclass is used to call it.PolymorphismIn an inheritance relationship, the ___________ is the specialized class.subclassSuppose a program uses two classes: Airplane and JumboJet. Which of these would most likely be the subclass?JumboJetIt is not possible to call a superclass's __init__ method from a subclass's __init__ method.Falsewhen two methods have the same name but do different tasks, one of the methods will override the other.When a subclass method has the same name as a superclass method, it is said that the method is overridden.A subclass can have a method with the same name as a method in the superclass.TruePolymorphism allows you to write methods in a subclass that have the same name as methods in the superclass.TrueYou cannot use the isinstance function to determine whether an object is an instance of a subclass of a class.FalseIn an inheritance relationship, the __________ is the general class.superclassOnly the __init__ method can be overridden.FalseYou can use this to determine whether an object is an instance of a class.the isinstance functionLook at the following class definition. What is the name of the superclass? What is the name of the subclass?: class Tiger(Felis):Felis is the superclass and Tiger is the subclass.
