Doing Math with Python shows you how to use Python to delve into high school–level math topics like statistics, geometry, probability, and calculus. You’ll start with simple projects, like a factoring program and a quadratic-equation solver, and then create more complex projects once you’ve gotten the hang of things. Along the way, you’ll discover new ways to explore math and gain valuable programming skills that you’ll use throughout your study of math and computer science. Learn how to: –Describe your data with statistics, and visualize it with line graphs, bar charts, and scatter plots –Explore set theory and probability with programs for coin flips, dicing, and other games of chance –Solve algebra problems using Python’s symbolic math functions –Draw geometric shapes and explore fractals like the Barnsley fern, the Sierpinski triangle, and the Mandelbrot set –Write programs to find derivatives and integrate functions Creative coding challenges and applied examples help you see how you can put your new math and coding skills into practice. You’ll write an inequality solver, plot gravity’s effect on how far a bullet will travel, shuffle a deck of cards, estimate the area of a circle by throwing 100,000 "darts" at a board, explore the relationship between the Fibonacci sequence and the golden ratio, and more. Whether you’re interested in math but have yet to dip into programming or you’re a teacher looking to bring programming into the classroom, you’ll find that Python makes programming easy and practical. Let Python handle the grunt work while you focus on the math. Uses Python 3

YOUR PRACTICAL, HANDS-ON GUIDE TO WRITING APPLICATIONS USING GO Google announced the Go programming language to the public in 2009, with the version 1.0 release announced in 2012. Since its announcement to the community, and the compatibility promise of the 1.0 release, the Go language has been used to write scalable and high-impact software programs ranging from command-line applications and critical infrastructure tools to large-scale distributed systems. It’s speed, simplicity, and reliability make it a perfect choice for developers working in various domains. In Practical Go - Building Scalable Network + Non-Network Applications, you will learn to use the Go programming language to build robust, production-ready software applications. You will learn just enough to building command line tools and applications communicating over HTTP and gRPC. This practical guide will cover: Writing command line applications Writing a HTTP services and clients Writing RPC services and clients using gRPC Writing middleware for network clients and servers Storing data in cloud object stores and SQL databases Testing your applications using idiomatic techniques Adding observability to your applications Managing configuration data from your applications You will learn to implement best practices using hands-on examples written with modern practices in mind. With its focus on using the standard library packages as far as possible, Practical Go will give you a solid foundation for developing large applications using Go leveraging the best of the language’s ecosystem.

Explore les mathématiques en codant ! Cet ouvrage va te montrer comment utiliser Python pour maîtriser des sujets du niveau fin de collège/lycée comme les statistiques, la géométrie, les probabilités et le calcul infinitésimal. Tu débuteras par des projets simples, comme créer un programme calculant la factorielle ou résolvant une équation quadratique, puis, une fois que tu auras appris les bases, tu pourras t''attaquer à des projets plus compliqués. Au fil de ta lecture, tu vas découvrir de nouvelles manières d''explorer les mathématiques tout en acquérant des compétences en programmation qui te serviront tout au long de tes études. Tu verras entre autres comment : décrire des données avec les statistiques et les organiser sous forme de courbes, diagrammes en bâtons ou de dispersion ; explorer la théorie des ensembles et les probabilités avec des programmes simulant des lancers de pièce et de dé, et autres jeux de chance ; résoudre des problèmes d''algèbre avec les symboles en Python ; tracer des formes géométriques et explorer les fractales comme la fougère de Barnsley, le triangle de Sierpinski et l''ensemble de Mandelbrot ; écrire des programmes calculant des dérivées et des intégrales de fonctions. Coder un programme résolvant des inégalités, tracer le graphique d''un projectile en mouvement, mélanger un paquet de cartes, estimer l''aire d''un cercle en jetant 100 000 fléchettes virtuelles sur une surface, explorer la relation entre la suite de Fibonacci et le nombre d''or, voilà ce qui t''attend dans ce livre et bien plus encore. Que tu sois intéressé par les mathématiques mais encore débutant en programmation ou que vous soyez un professeur cherchant à introduire la programmation dans vos cours, vous verrez que Python rend la programmation simple et pratique.

The ''Children of Glowworm'' by Amit Saha explores the world of autism, the life of the children with autism, and the agony and struggle of their parents, and families. Amit himself, being the father of an autistic son, fills the pages with genuine feelings and experience to weave an intriguing and effortless story. This novella set in Bolpur, a small town in West Bengal, India vividly portrays the life of the protagonists spanning through the last decade. Amit makes us realize that autism is not a disease, but a certain genetic condition or developmental disorder, that Neer, Piku, and Rishi, are of course different from other children, but they do have a beautiful world of their own: they can think purely, can observe and feel the nature closely, can write story or poem, can paint, and at times they outdo their normal counterparts. The ''Special Children'' is nothing but a mere convention or rather our unawareness. They are not doomed, nor are their parents. This novella is a kind of autistic awareness campaign in the guise of a painful journey of life. This novella reveals the stark reality of how the so-called normal society pushes the victims and their kin to spiritual crises which serves as the conflict of the story. Whether these children and the family get a better world or not, whether their dream comes true or not drives the story forward, and how the normal world reacts to them is the resolution of the story. Will Piku, Rishi, and the like get a better world to live in? Will Piku, Rishi, and Neer''s and their parent''s pensive journey end in light? What do these children think about us when they overhear ''Special Children''? What if they think of us being special people? The novella forces us to encounter these questions. It''s a journey of life from darkness to light.
