(This tutorial is based on the practical development and application of artificial intelligence. The book is divided into three parts, a total of 18 chapters. The first part is scratch programming. Chapter 6, including scratch, systematically introduces the instructions and methods in the primary logic programming of artificial intelligence. Instruction introduction, programming example introduction and high-level logic comprehensive programming; The second part is the tutorial of artificial intelligence Python advanced programming language. Chapter 8 systematically introduces the basic syntax of python, object-oriented Python advanced programming, GPIO library, etc; The third part is the practical programming of artificial intelligence development system. It is divided into four chapters to introduce the experiments of various sensors and the comprehensive experiment based on artificial intelligence advanced programming.This tutorial is written in combination with the application practice of artificial intelligence. All practical developments of artificial intelligence have been verified by experiments and can be directly applied to artificial intelligence and Internet of things related fields."Artificial intelligence development and practical application" emphasizes practicality and readability. It can be used as the teaching material of artificial intelligence education for all kinds of students, as well as the teaching material for readers of computer, information processing, automation, artificial intelligence and other related majors. It can be used as a reference for teaching and scientific researchers engaged in computer science research, development and application.)
