Building an Idempotent Payment System with Spring Boot & React

Payment systems are at the core of modern web applications, but they come with a tricky problem: duplicate transactions. Whether it’s a user accidentally clicking “Pay” twice or a network retry causing multiple API calls, duplicate charges can quickly erode trust and create operational headaches. In this blog, I’ll walk you through a full-stack idempotency … Continue reading Building an Idempotent Payment System with Spring Boot & React

Understanding Constructors in Python

In Python, a constructor is a special method named __init__() that is automatically called when an object of a class is created. The primary purpose of the constructor is to initialize the instance variables of the object. Let's delve deeper into the key concepts surrounding constructors in Python.

Understanding Classes and Objects in Python:

In Python, classes serve as blueprints for creating objects, encapsulating data and behavior. Objects are instances of classes, representing specific entities with unique attributes and methods. Through classes and objects, Python supports the principles of object-oriented programming, facilitating modular and reusable code.

Python Operators

Python operator is a symbol that performs an operation on one or more values or variables. For example, the addition operator + adds two numbers together, the subtraction operator - subtracts one number from another, and so on. Python provides various types of operators such as arithmetic operators, comparison operators, logical operators, assignment operators, etc., each serving a specific purpose in manipulating data or controlling program flow.
