If you want to move beyond basic syntax and truly level up your coding skills, you must practice Python OOP exercises.

Object-Oriented Programming (OOP) is one of the most important concepts in Python. Most real-world applications, frameworks like Django, and technical interviews require strong OOP knowledge.

In this guide, you’ll solve practical Python class practice problems covering:

• Classes and Objects

• Constructors

• Inheritance

• Polymorphism

• Encapsulation

If you’re following a structured roadmap of Python exercises for beginners to advanced, OOP is the turning point from beginner to professional level.

Python Exercises for Beginners to Advanced (300+ Practice Problems)

Why Practice Object-Oriented Programming in Python?

OOP helps you:

• Organize code into reusable components

• Build scalable applications

• Prepare for software engineering roles

• Understand frameworks like Django

• Crack coding interviews

Without mastering OOP, it’s difficult to move into advanced Python development.

1️⃣ Classes and Objects Exercises

Exercise 1: Create a Basic Class

Create a class Student with attributes name and marks.

<br />
class Student:<br />
    def __init__(self, name, marks):<br />
        self.name = name<br />
        self.marks = marks</p>
<p>s1 = Student(&quot;Ali&quot;, 85)<br />
print(s1.name, s1.marks)<br />

This is a fundamental Python class exercise every beginner must practice.

Exercise 2: Add a Method to a Class

Add a method that prints student details.

2️⃣ Inheritance Exercises

Inheritance allows one class to reuse another class’s functionality.

<br />
class Student:<br />
    def __init__(self, name, marks):<br />
        self.name = name<br />
        self.marks = marks</p>
<p>    def display(self):<br />
        print(f&quot;Name: {self.name}, Marks: {self.marks}&quot;)</p>
<p>s1 = Student(&quot;Sara&quot;, 92)<br />
s1.display()<br />

Exercise 3: Implement Inheritance

<br />
class Person:<br />
    def greet(self):<br />
        print(&quot;Hello!&quot;)</p>
<p>class Teacher(Person):<br />
    def subject(self):<br />
        print(&quot;I teach Python.&quot;)</p>
<p>t1 = Teacher()<br />
t1.greet()<br />
t1.subject()<br />

This type of Python OOP practice problem is frequently asked in interviews.

3️⃣ Polymorphism Exercises

Polymorphism allows methods to behave differently depending on the object.

Exercise 4: Method Overriding

<br />
class Animal:<br />
    def sound(self):<br />
        print(&quot;Animal makes sound&quot;)</p>
<p>class Dog(Animal):<br />
    def sound(self):<br />
        print(&quot;Dog barks&quot;)</p>
<p>d = Dog()<br />
d.sound()<br />

Understanding polymorphism is critical for advanced software development.

4️⃣ Encapsulation Exercises

Encapsulation restricts access to certain variables.

Exercise 5: Private Variable Example

<br />
class BankAccount:<br />
    def __init__(self, balance):<br />
        self.__balance = balance</p>
<p>    def get_balance(self):<br />
        return self.__balance</p>
<p>account = BankAccount(5000)<br />
print(account.get_balance())<br />

This improves code security and structure.

5️⃣ Advanced OOP Challenge

Exercise 6: Create a Simple Banking System

Create a class that:

• Deposits money

• Withdraws money

• Checks balance

<br />
class BankAccount:<br />
def __init__(self, balance):<br />
self.__balance = balance</p>
<p>def get_balance(self):<br />
return self.__balance</p>
<p>account = BankAccount(5000)<br />
print(account.get_balance())<br />

These are real-world style advanced Python exercises.
