Although this is an introductory book, the "ambition" of this book is not limited to the "primary level" teaching. The first half of this book first explains the basic grammar knowledge of Python 3, including linked lists, tuples, strings, dictionaries and various sentences. Then gradually introduce some relatively advanced topics, including abstraction, exception, magic method and attribute iterator. The second half focuses on the application of Python 3 in reptile, interface development and game development, and guides readers to study and explore deeply through examples, which is both interesting and practical.
