• To create a new attribute

What is the purpose of a setter method in Python?

• To access the value of an attribute

• To modify the value of an attribute with validation

• To delete an attribute

• To initialize an attribute

What is compile-time polymorphism in programming languages?

• Polymorphism achieved through function overloading

• Polymorphism achieved through method overriding

• Polymorphism achieved through operator overloading

• Polymorphism achieved through dynamic method dispatch

How does Python handle operator overloading?

• By defining special methods like __add__, __sub__, etc.

• By using function overloading

• By using method overriding

• By using access control modifiers

Which of the following methods would you override to enable addition between two custom objects in Python?

• __eq__

• __add__

• __sub__

• __mul__

What does the @property decorator in Python do?

• It defines a method that can be used as a setter

• It defines a method that can be used as a getter

• It makes a method act as both a getter and setter

• It hides a method from being accessed

Which of the following is true about the __str__ method in Python?

• It is used for debugging purposes

• It is used to represent the object in a human-readable format

• It is used for comparing objects

• It is used for performing arithmetic operations

In Python, what method would you use to override the behavior of the + operator for a custom class?

• __mul__

• __add__

• __sub__

• __truediv__

What is the role of the @staticmethod decorator in Python?

• It defines a method that does not have access to the instance (self) or class (cls).

• It allows a method to be called on the class itself, but not on instances of the class.

• It defines a method that can modify instance attributes.

• It defines a method that can only be called on an instance.

How does Python achieve method overloading?

• By defining multiple methods with the same name but different parameters.

• By using default arguments and variable-length argument lists.

• By using method decorators.

• By defining methods with the same name but different return types.
