A dictionary in Python is a collection of key-value pairs. It is unordered, mutable, and indexed by keys — which can be strings, numbers, or even tuples (if immutable). Let’s begin exploring with the Python shell open. lang = { "c++": "easy", ...
Strings are one of the most fundamental data types in Python. Whether you're printing a message, processing user input, or working with file paths — you're dealing with strings. In this blog, we’ll explore everything from string slicing and built-in ...
Python’s number system isn’t just about int and float. In fact, numbers in Python include a rich collection of types such as decimals, fractions, complex numbers, and even booleans and sets. Let’s explore how Python treats and manipulates these data ...
Question: Given an array of integers nums and an integer target, return the indices of the two numbers such that they add up to the target. Constraints: Each input would have exactly one solution. The same element cannot be used twice. Examples: ...
The Factory Method pattern is a creational design pattern that provides an interface for creating objects in a super class but allows subclasses to alter the type of objects that will be created. It promotes loose coupling and flexibility in object c...
In my previous blog, you learned the basics of Python. So now let's dive deep into file handling in Python. So file handling is an important part of any web application. Python has several functions for creating, reading, updating, and deleting files...
Python basics cover the fundamental concepts and features of the Python language that you need to know to get started with Python programming. The main topics covered in Python basics are: 1. Syntax Python uses fairly conventional syntax with some un...
1. Why Learn Python In The First Place Python is a powerful programming language yet extremely simple to learn. It is built around the philosophy of minimal code to get the same work done. Let's get an intuition of the same using an example: 1.1) Hel...
Exercise 1: Greeting Program Write a program that asks the user for their name and then prints a personalized greeting. The program should display a message like "Hello, [name]!" where [name] is the name entered by the user. Exercise 2: Even or Odd W...
Welcome back! Today, we're going to take our first step in programming by exploring variables. Our goal is to familiarize ourselves with them and learn how to use them in our code. Then, we'll build a program to see how variables work in practice. ht...
