If you’re learning Python and want to test your understanding of Python classes you are in the right place, this quiz is perfect for you. Classes are the building blocks of object-oriented programming in Python, helping you organize code into reusable structures. In this Python Class Quiz – 15 Questions, you’ll get a chance to solve beginner-to-intermediate level problems that focus on creating classes, initializing objects, using methods, inheritance, and more. By the end, you’ll know exactly which areas you’ve mastered and where you need more practice.

Things Covered in This Quiz

In this quiz, you’ll practice and improve your skills in:

• Defining Python classes and creating objects
• Using __init__ constructors
• Working with instance and class variables
• Writing and calling class methods
• Understanding inheritance and method overriding
• Using built-in class functions like __str__
• Applying @staticmethod and @classmethod decorators

1. What is the correct way to define a class in Python?

class MyClass:
    pass

This is correct class MyClass[]: pass class: MyClass pass

2. What does the __init__ method do in a class?

Deletes the object Initializes object attributes Creates a class variable

3. What will be the output?

class Test:
    def __init__(self):
        print("Hello World")

obj = Test()

Hello World No output Error

4. How do you create an object of a class named Student?

Student = object() Student.object() obj = Student()

5. What will this print?

class MyClass:
    def greet(self):
        return "Hi!"

obj = MyClass()
print(obj.greet())

Hi! greet Error

6. Which keyword is used for inheritance in Python?

inherits class Child(Parent): extend Parent

7. What will be the output?

class Car:
    wheels = 4

print(Car.wheels)

4 wheels Error

8. What does the @staticmethod decorator do?

Creates a method that does not need self Makes the method private Deletes the method

9. Which is correct to define a class variable?

Defined outside all methods in a class Defined inside __init__ Defined in main()

10. Output?

class A:
    def __str__(self):
        return "Class A"

obj = A()
print(obj)

Class A obj Error

11. What will happen?

class Test:
    pass

print(isinstance(Test(), Test))

True False Error

12. How do you call a parent class method in a child class?

super().method_name() parent.method() self.parent()

13. What is true about __del__?

It is called when an object is deleted It deletes a class variable It deletes __init__

14. Which is correct for multiple inheritance?

class C(A, B): class C(A & B): class C(A+B):

15. Which is true about instance methods?

They take self as the first parameter They take class as the first parameter They have no parameters

Conclusion

You’ve now completed the Python Class Quiz – 15 Questions and tested your skills on the fundamentals of Python classes. If you scored high, great job — you’re ready to tackle more advanced OOP concepts like polymorphism, abstraction, and design patterns.
