Python - Object-Oriented Programming - Getters and Setters

The video tutorial explains encapsulation in object-oriented programming using a TV example. It introduces getter and setter methods to interact with private attributes in a class. The tutorial demonstrates how to implement these methods, including validation checks in setters using assert and raise functions. The video concludes with a summary of the concepts covered.

What is the primary purpose of encapsulation in object-oriented programming?

• To hide the complexity and provide a simple interface

• To eliminate the need for classes

• To increase the complexity of the code

• To make all attributes public

What is a getter method used for?

• To create a new attribute

• To return the value of an attribute

• To delete an attribute

• To modify the value of an attribute

Why are setter methods important in classes?

• They are used to delete attributes

• They automatically generate new attributes

• They enable validation checks before setting attribute values

• They allow direct access to private attributes

What is the role of validation checks in setter methods?

• To ensure the attribute value is always zero

• To prevent the method from being called

• To ensure the new value is valid before assignment

• To allow any value to be set without restrictions

What happens if an invalid value is passed to a setter method with validation?

• A ValueError is raised

• The program crashes immediately

• The value is set without any error

• The attribute is deleted

What is the main difference between getter and setter methods?

• Getters modify attributes, setters return attributes

• Getters return attribute values, setters modify attribute values

• Getters delete attributes, setters create attributes

• Getters and setters perform the same function

Why is it important to use getter and setter methods for private attributes?

• To provide controlled access and maintain data integrity

• To eliminate the need for classes

• To make the code more complex

• To allow unrestricted access to attributes
