Week 7-8

What is method overriding?

• Changing the way a method works in a subclass.

• Increasing the speed of a method.

• Deleting a method from a superclass.

• Renaming a method in a subclass.

What is association in Python?

• Error handling technique.

• Relationship between classes where one class uses the functionalities of another class.

• A special method in Python.

• A way to import libraries.

What does the method _init_ do in Python classes?

• Initializes a newly created object.

• Acts as a destructor for objects.

• Is called when an object is inherited.

• Initializes static variables.

What does the 'super()' function do?

• It enhances the speed of functions.

• It is used to call a method from a sibling class.

• It returns a proxy object that delegates method calls to a parent or sibling class.

• It is used to terminate a program.

Which statement about method overloading in Python is true?

• Python does not support method overloading by default.

• Method overloading is the same as method overriding.

• Python requires a special operator for method overloading.

• Method overloading can only be done in subclasses.

How do you define a private variable in a Python class?

• By using the private keyword.

• By prefixing the variable name with two underscores __.

• By prefixing the variable name with a single underscore _.

• By using the private method.

Can a Python class inherit from multiple classes?

• Yes, but only if the classes are abstract.

• No, Python supports only single inheritance.

• No, this feature is not available in Python.

What is the purpose of the _str_ method in Python?

• It is used for adding two objects together.

• It is used to return a string representation of an object.

• It is used to compare two objects.

• It initializes an object.

How can you access a base class method from a derived class that has overridden the method?

• By calling base_class.method_name().

• By renaming the base class method.

•  By calling method_name() without any prefix.

• By calling super().method_name().

Which of the following is an advantage of using inheritance?
