Don't trust them! Python in Zhonggu really sucks! It's not like this after paying the money! Don't sign up, I'm the victim! The lesson of blood! If you really want to learn development, find another home! A dishonest educational institution, when you need after-sales service, people will tell you that "we are not the company that collected your money at the beginning"! Stay away from the valley, and the fewer people who want to suffer, the better! Remember never to pay!
