(Python is a simple and powerful programming language, which is widely used in data analysis, big data, web crawler, automatic operation and maintenance, scientific computing, artificial intelligence and other fields. Python is also becoming more and more important and has become a subject of the national computer grade examination. Some primary and secondary schools have also set up python programming courses. Adhering to the concept of being interesting, informative, interesting and easy to use, this book simplifies complex Python technical problems through three comic characters' easy dialogue, interesting images and exaggerated actions.)
