My friend asked me how to quickly master python. I want to write a quick Python tutorial similar to the w3cschool style by adding a variety of standard libraries and expanding libraries, on the one hand, keep the words concise, and on the other hand, gradually make it possible for readers without background to start learning from the basics. In addition, I concentrate on a small concept in every article, ho
