View

What is the primary role of the constructor (__init__) in Python?

To delete unused objects
To initialize the object’s attributes
To destroy objects
To create a new class

Can a class have more than one constructor?

Yes, by defining multiple __init__ methods
Yes, by using method overloading
No, only one constructor is allowed
Only with abstract classes

What is a destructor in Python?

A function that destroys data
A method to delete attributes
A special method that is called when an object is deleted
A private method for memory management

Which method acts as the destructor in Python?

__init__()
__del__()
__destroy__()
__finalize__()

When is the destructor method invoked?

When the object is initialized
When the object goes out of scope or is deleted
When the program starts
When a method is overridden

What happens if __init__ is not defined in a class?

The class cannot be instantiated
Python provides a default constructor
An error is raised
The class must be abstract

What is the correct way to invoke the parent class’s constructor?

Using parent.__init__()
Using super().__init__()
Using self.__init__()
Using init()

Can a constructor call other methods within the class?

Yes
No
Only if the method is public
Only if the class is inherited

Why are constructors useful in Python?

They make classes compile faster
They initialize an object’s state upon creation
They delete unneeded data
They avoid memory leaks

Which statement best describes the relationship between constructors and destructors?

Constructors initialize an object, while destructors release its resources
Constructors and destructors have identical roles
Destructors run before constructors
Only constructors are needed in Python
