FGWHN Python OOP - Polymorphism

What is polymorphism in OOP?

• A way to create classes and objects.

• The ability of an object to take on many forms.

• A type of variable in Python.

• A way to sort elements in Python.

How is polymorphism implemented in Python?

• Through using multiple inheritance.

• By using the polymorphic keyword.

• Through defining different classes with the same method names.

• Python doesn't support polymorphism.

What is a key feature of polymorphism?

• Objects of different types can be passed to the same function.

• All objects must be of the same type.

• Only integers and strings can be used with polymorphism.

• Polymorphism is only applicable to data structures.

In Python, why is polymorphism useful with inheritance?

• It allows objects from a child class to be treated as objects from a parent class.

• It is required for inheritance to work.

• It makes the code less readable.

• Polymorphism is not useful with inheritance.

What is the output?

• "Drawing a shape"

• "Drawing a circle"

• Error, invalid method call.

• None of the above.

Given the following code, how would you call the speak function to print "Hello"?

• speak(English())

• speak(Spanish())

1. 
   What will be the output of the following Python code?

• 100 km/h

• 150 km/h

• Error, invalid method call.

• None of the above.

What is an abstract method?

• A method that has a declaration but does not have an implementation.

• A method that can be called directly from the class.

• A method that cannot be overridden in a subclass.

• A method that is automatically called when a class is instantiated.

What is the output?

• The subclass is doing something

• Error, the do_something method in AbstractClassExample is not implemented.

• Nothing, the program does not print any output.

• Error, you cannot instantiate an abstract class.

What is the main purpose of an abstract class in OOP?

• To serve as a base class for other classes

• To create objects and instances so later we can use

• To define & implement basic features for sub classes

• To handle exceptions
