In this post, we’ll explore Numeric Data Types in Python, which are fundamental to any program that involves calculations, counting, or number manipulation. Specifically, we’ll cover integers, floating-point numbers, and briefly mention complex numbers. Let’s dive in. Python’s Three Primary Numeric Data Types Python provides three core numeric types: Integers (int) Floating-point numbers (float)...
Problem: #2 adding two numbers LeetCode #2 solution – Adding Two Numbers: You are given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order, and each of their nodes contains a single digit. Add the two numbers and return the sum as a linked list. You may assume the two numbers do not contain any leading zero, except...
Problem: 1 two sum Leetcode #1 solution – Two Sum: Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. You may assume that each input would have exactly one solution, and you may not use the same element twice. You can return the answer in any order. Examples: Input: nums = [2...
In this comprehensive guide, I’ll introduce you to objects in Python. This is an essential concept because, in Python, everything is an object. What are Objects in python? An object in Python is like a package that holds both data and functionality. It contains: Data: Numbers, text, lists, or any other type of value. Methods: Functions that belong to the object, allowing you to interact...
Data types are one of the fundamental concepts in programming. In Python, understanding data types is crucial for writing effective and efficient code. This guide will delve into what data types are, why they are important, and how Python’s dynamic typing system works. What Are Python Data Types? At its core, a data type defines the kind of value a variable can hold. It tells Python—and...
Operators are one of the foundational concepts in any programming language, and Python is no different. They allow you to perform operations on variables and values, whether it’s basic math, comparing numbers, or performing complex bitwise manipulations. In this post, we’ll explore the different types of Python operators and understand their usage. We’ll cover unary, binary, and ternary...
Hi, I’m Peter, a professional developer with over 25 years of experience. My journey with coding started when I was just a kid, exploring the world of programming and building my first projects out of pure curiosity and passion. Since then, I’ve turned this lifelong passion into a rewarding career, working on a wide range of projects, from small scripts to complex applications.
Now, I’m here to help others get started with coding through this blog. I know that learning to code can feel overwhelming at first, but I believe that with the right guidance, anyone can develop the skills they need to become a proficient programmer. My goal is to simplify the learning process and provide step-by-step resources that make coding accessible, fun, and practical for everyone.
Whether you’re just starting out or looking to sharpen your skills, I hope this blog serves as a valuable resource on your coding journey. Let’s dive into Python together!
