Presumably many friends who are learning Python have been unable to do anything. Once they learn it, they will lose it when they get started.
That's because you didn't have a direction when you were studying.
So, in a day's time, I have listed all the knowledge points to be learned in the basics of Python for you in order.
Friends who are not good at basic learning or who are just starting to learn Python can take a good look at it
