Understanding Inheritance in OOP 3

What is inheritance in OOP?

• Inheritance allows classes to be combined into a single class.

• Inheritance is a method for storing data in a database.

• Inheritance is a way to create multiple instances of a class.

• Inheritance is a mechanism in object-oriented programming that enables a new class to inherit attributes and behaviors from an existing class.

How do you define a child class in Python?

• class ChildClassName extends ParentClassName

• class ChildClassName: ParentClassName

• class ChildClassName inherits ParentClassName

• class ChildClassName(ParentClassName):

What is the purpose of inheritance?

• To increase the complexity of code

• To create multiple instances of a class

• To limit access to class members

• The purpose of inheritance is to enable code reuse and establish a relationship between classes.

What is the super() function? How is it used?

• The super() function is used to create new classes in Python.

• The super() function is a built-in function for error handling.

• The super() function is used to define global variables in Python.

• The super() function is used to call methods from a parent class in Python.

Can a child class override a parent class method? Provide an example.

• A child class can only inherit methods, not override them.

• Only static methods can be overridden by child classes.

• Yes, a child class can override a parent class method.

• No, a child class cannot override a parent class method.

What is multiple inheritance? How is it implemented in Python?

• In Python, multiple inheritance is implemented using interfaces only.

• Multiple inheritance allows a class to inherit from multiple parent classes, implemented in Python by specifying multiple parent classes in the class definition.

• Multiple inheritance allows a class to inherit from a single parent class.

• Multiple inheritance is not supported in Python.

What is the isinstance() function used for?

• The isinstance() function is used to convert data types.

• The isinstance() function is used to create new objects.

• The isinstance() function is used to check the type of an object.

• The isinstance() function is used to delete objects.

What is the issubclass() function used for?

• The issubclass() function checks if two classes are identical.

• The issubclass() function retrieves the attributes of a class.

• The issubclass() function is used to create a new class.

• The issubclass() function is used to determine if a class is a subclass of another class.

What is the difference between single and multiple inheritance?

• Single inheritance involves one superclass, while multiple inheritance involves multiple superclasses.

• Single inheritance allows for multiple superclasses.

• Multiple inheritance is only used in functional programming.

• Single inheritance can involve multiple subclasses.

Write an example of hierarchical inheritance.

• Vehicle -> Car -> Sedan

• Animal -> Mammal -> Dog

• Animal -> Reptile -> Lizard

• Plant -> Flower -> Rose
