First of all, let's take a look at what is the principle of WeChat remote control of the computer?
We can use Python's standard library to control the local computer. If we want to achieve remote control, we can use email as a remote control channel. We use Python to automatically log in to the mailbox to detect emails. When we send a shutdown command to this mailbox, if Python detects the relevant command, then Python directly sends the relevant command of the machine.
Let's analyze the project:
1. Requirement analysis
1. Scope: use Python to develop a project to remotely control a computer.
2. General requirements:
2.1 General functional requirements: The software can remotely control the restart or shutdown of the computer where the software is located.
2.2 System requirements: Python is used as the development language, and the developed programs can run on Windows.
2. Design
First, we can use Python's standard library to control the local computer, and then to achieve remote control, we can use email as a remote control channel, we use Python to automatically log in to the mailbox to detect emails, and when we send a shutdown command to this When the mailbox is used, if Python detects the shutdown command, Python directly sends the shutdown of the machine.
3. The flow chart for writing
this project is as follows . The 
first step is to register a Sina mailbox. Then click on Sina mailbox, click the settings in the upper right corner and 
select "client pop/imap/smtp" as shown in the figure to 
open the SMTP and POP3 functions of Sina mailbox. 
Specific implementation code:
configuration file config.ini
[Slave] pophost = pop.sina.com smtphost = smtp.sina.com port = 25 username = [email protected] password = XXX [Boss] mail = [email protected] timelimit = 2 [Command] shutdown=shutdown -f -s -t 100 -c closing... you=you [Open] music = F:Masetti - Our Own Heaven.mp3 video = F: Jai Waetford - Shy.mp4 notepad = notepad

4. Summary
In the process of writing this small project, I know the basic process of project development and walk through it, develop the project through project management, and review some Python in the process of developing this small project Basic knowledge in the primary stage, and a deeper understanding of the steps from project design to project implementation, as well as project test operation and maintenance, require a deep understanding of programmers, so that they can gradually improve themselves in the project.
