Introduction In Python, you can use multiple except blocks to handle different types of exceptions separately. This allows your program to respond appropriately to various errors that might occur during execution. Each except block catches a specific type of exception, enabling you to provide tailored error messages or handle the errors in different ways. This …
Introduction In Python, you can raise custom exceptions to handle specific situations in your program that aren’t covered by the built-in exceptions. Custom exceptions allow you to define and manage errors specific to your application’s logic. This is done by creating a new exception class that inherits from Python’s built-in Exception class or one of …
Introduction In Python, the try, except, and finally blocks are used for exception handling. These blocks allow you to handle errors gracefully without crashing your program. The try block contains code that might raise an exception, the except block handles specific exceptions that might occur, and the finally block contains code that will execute no …

Introduction In programming, exceptions are errors that occur during the execution of a program. One common exception is the ZeroDivisionError, which occurs when a number is divided by zero. To handle such exceptions gracefully, Python provides a try-except block, which allows you to manage errors and prevent your program from crashing unexpectedly. This tutorial will …

Introduction In object-oriented programming, a class method is a method that is bound to the class and not the instance of the class. Class methods can modify class state that applies across all instances of the class. They are often used to create factory methods or modify class-level variables. Class methods in Python are defined …
Introduction Abstraction is a fundamental concept in object-oriented programming (OOP) that focuses on hiding the implementation details and showing only the essential features of an object. This allows the user to interact with the object at a higher level without needing to understand the complexity of its inner workings. In Python, abstraction is typically implemented …
Introduction Encapsulation is one of the fundamental concepts in object-oriented programming (OOP). It refers to the bundling of data (attributes) and methods (functions) that operate on the data into a single unit, or class. Encapsulation restricts direct access to some of an object’s components, which is a means of preventing unintended interference and misuse of …
Introduction Polymorphism is a key concept in object-oriented programming that allows objects of different classes to be treated as objects of a common superclass. It enables methods to be used in different ways based on the object that is invoking them. Polymorphism allows for the design of flexible and reusable code because the same method …
Introduction Method overriding is a feature of object-oriented programming that allows a subclass to provide a specific implementation of a method that is already defined in its superclass. The method in the subclass should have the same name, return type, and parameters as the method in the superclass. When a method is overridden, the version …
Introduction Multiple inheritance is a feature of object-oriented programming where a class can inherit attributes and methods from more than one parent class. This allows a child class to combine the functionality of multiple parent classes. However, multiple inheritance can also lead to complexity, especially when different parent classes have methods with the same name. …

Introduction Inheritance is a fundamental concept in object-oriented programming (OOP) that allows a new class (called the child or subclass) to inherit attributes and methods from an existing class (called the parent or superclass). This enables code reuse and the creation of hierarchical class structures, where specialized classes share common behavior from more general classes. …
Introduction Classes and objects are fundamental concepts in object-oriented programming (OOP). A class is a blueprint for creating objects (instances), providing initial values for state (member variables or properties) and implementations of behavior (member functions or methods). An object is an instance of a class, containing real data that the class blueprint defines. This tutorial …

Introduction The Tower of Hanoi is a classic problem in computer science and mathematics that involves moving a stack of disks from one rod to another, following certain rules. The problem consists of three rods and a number of disks of different sizes, which can slide onto any rod. The puzzle starts with the disks …

Introduction The Greatest Common Divisor (GCD) of two numbers is the largest positive integer that divides both numbers without leaving a remainder. The GCD is also known as the greatest common factor (GCF) or the highest common factor (HCF). One of the most efficient algorithms to find the GCD is Euclid’s algorithm, which can be …
Introduction The Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones, usually starting with 0 and 1. The sequence typically starts as follows: 0, 1, 1, 2, 3, 5, 8, 13, 21, …. In mathematical terms, the Fibonacci sequence is defined as: F(0) = 0 F(1) …

Introduction Recursion is a programming technique where a function calls itself to solve smaller instances of a problem until a base condition is met. Recursive functions are particularly useful for solving problems that can be broken down into smaller, similar sub-problems, such as calculating factorials, generating Fibonacci sequences, and traversing trees. This tutorial will guide …
Introduction Default arguments in Python allow you to define a function with default values for one or more parameters. This feature is useful when you want to make some parameters optional or provide a default behavior if no argument is provided for those parameters. This tutorial will guide you through creating a Python program that …
