Pygame's Chinese chess has always been fond of playing chess. When we write python, we will try it. The level of computer walking is limited and the level of computer walking is low. We need to update the computer walking in the next version. We hope that the source code can help you learn Python better. There are four files in total: chinachess.py as the main file, constants.py as the data constant, pieces.py as the chess sub class, walking method, and computer.py as the computer walking method.

PS: in the process of learning python, many people often give up because they can't solve problems or don't have good tutorials. Therefore, I sorted out the basic Python script, web development, crawler, django, data mining and other [PDF] needs, which can be used in the full stack of Python development and communication. Skirt: after a long time of martial arts, you can find it under the conversion of thinking (Digital homophony) Here we are. There are the latest Python tutorial projects to take. The problems that we don't understand can be solved by the old driver. We can supervise each other and make progress together
