Preface
Recently, many kids who have learned the basics asked me how to improve my programming level ？ What should I do after learning the basics ？ Mingming learned a lot , Do the project but don't know how to get started , In fact, this is too little practice , Only pay attention to learning , But ignore the question , Only continuous practice can improve and consolidate programming thinking and ability ！
I happened to see that niuke.com has recently released Python So I had a good experience with my new question bank
