Introduction
Hello! Hello, I'm Mengya.
Whether home computers or company computers, timing on-off is a very practical function, but it is generally not paid much attention. Timed shutdown can not only prolong power consumption
The service life of the brain can save too much electricity ~ ha ha ha
Hi ~ no, I take a day off on Sundays, but most of the company's computers are on for a day. Sometimes when I have a long holiday, the computer is on for a few days.
see? The little sister next door has been discovered by the leader, and the last thing falls into my hands. Develop one that can close regularly
Machine source code project for everyone to use, and remind each other that everyone must shut down after work!
Timing switch is a very simple and practical function. You can learn how to operate it in less than 10 minutes~

This article introduces: ordinary people's habit of shutting down, and programmers' way of shutting down, ha!
And the programmer shut down and attached two copies of code. If you like tkinter, use tk version, and if you like pyqt5, use this version. Two versions are large
I love to use that at home~
1, Ordinary people shut down
0) graceful shutdown
1) Shortcut key shutdown
Use the shortcut key to shut down, I believe it is a more commonly used method? It is also the simplest and most convenient method.
Press the shortcut key [Alt] + [F4] to pop up the function dialog box to realize fast and accurate shutdown, with high efficiency.
2) Task manager shutdown
This method is similar to the previous shortcut key shutdown method. Press the shortcut key [Alt] + [Ctrl] +
[Delete] open the task manager. There is a circular shutdown button at the lower right. Click it to shut down.
3) Set shutdown time
This method can realize regular shutdown, calculate the time you want to shut down, and the computer will shut down automatically at point after setting. Never again
I've been waiting for a long time because the computer is turned off and updated. Press the shortcut key [win] + [R], and enter "at20:00" in the operation dialog box
Click OK after "shutdown-s" and the system will shut down on time at 8 p.m. This method can be used to determine the shutdown time
It is very convenient to use in the case of.
4) Mouse sliding shutdown
Create a shortcut on the computer desktop, enter "slide to shutdown" in the dialog box that appears, and then click next.
Click finish.
At this time, there is a shortcut on the computer desktop. When you want to shut down, double-click the shortcut, and the following prompt will appear. Just slide
The computer has been turned off.
2, Programmer shutdown
Although it is true that normal people can switch on and off the machine more conveniently and quickly, ha! But it's more convenient to package the source code into exe, especially when the computer needs to be shut down after a few hours. It's quite convenient to let the computer automatically complete the task before shutting down. Maybe it should be more convenient. jpg forcibly explained me 2333. This is the code of entertainment. Hahaha. Finally, if you don't have a lot of time and want to improve python quickly, The most important thing is that you are not afraid of hardship. I suggest you can the price (homonym): 762459510. That's really good. Many people make rapid progress. You need to be not afraid of hardship! You can add it and have a look~

summary
Well, the small project of regular shutdown is over. Remember to use this code if you need to shut down regularly in the future. Hahaha ~ shut down whenever you want
