Description

Pythonis an interesting programming language with great possibilities. Thanks to it you can easily solve complex problems of this world. At the same time, it allows you to write clear and easy to maintain code. Mastering the syntax and basic programming concepts in Python is not difficult, but then comes the moment to try it in real programming.

This book will teach you how to use this language to solve nontrivial problems that programmers have to face. The book consists of fourteen fun and inspiring projects that will help you discover the nuances of programming and learn to work with several Python libraries. More importantly, you will learn how to analyze a problem, how to develop an algorithm to solve it, and then how to implement a solution. You will use Python to create music, simulate real-world phenomena, and you will be forced to work withArduino and RaspberryPi -allin a great, immersive way!

Examples of issues covered in the book:

generating spirographic patterns
making music on the computer
Translating images into ASCII art
create realistic animations using theOpenGLlibrary
3D visualisation ofCTandMRImedical imaging data
build an internet-based weather monitoring systemusing Raspberry Pi

Sample programsavailable on the Internet. Extract from a book to beread on-line.
