python定时开关机的代码_Python实现Windows定时关机
#ui制作：
照旧，笔者由Qt制作完成需要的ui，包括label,label_2,label_3,lable_4,lineEdit,lineEdit_2,pushButton组件.大致布局如下
两个lineEdit等待用户输入期望关机的时间。下面的Label用来显示操作后的返回信息。pushButton用于提交命令。ui制作完成。
#ui转为py文件：
这里笔者装的是PyQt5，并添加了环境变量。所以转化的cmd命令(cd到ui所在目录)：
pyuic5 shut.ui -o shut.py
1
pyuic5 shut.ui-oshut.py
执行成功之后在ui所在目录生成shut.py文件。
#显示窗口：
直接生成的py文件运行是看不到窗口的，我们要加上一些必要的内容才能显示我们的窗口：
代码最上面加上
import sys
1
import sys
最后加上
if __name__ == '__main__':
app = QtWidgets.QApplication(sys.argv)
Form = QtWidgets.QWidget()
ui = Ui_x()//其中Ui_x为生成的class名
ui.setupUi(Form)
Form.show()
sys.exit(app.exec_())
1
2
3
4
5
6
7
if__name__=='__main__':
app=QtWidgets.QApplication(sys.argv)
Form=QtWidgets.QWidget()
ui=Ui_x()//其中Ui_x为生成的class名
ui.setupUi(Form)
Form.show()
sys.exit(app.exec_())
之后再运行shut.py就能看到窗口了。
#功能实现：
思考一下程序的期望功能，使Windows自动关机。cmd命令是个不错的选择。于是笔者找了下，python执行cmd命令的方法：
os.popen('at 22:30 shutdown -s')
1
os.popen('at 22:30 shutdown -s')
调用cmd，执行命令。而其中的22和30是等待用户输入的数据。因此，应该用两个lineEdit中获取到的合法数字替换对应的h和m。用到获取lineEdit内容的方法：
h = self.lineEdit.text()
m = self.lineEdit_2.text()
1
2
h=self.lineEdit.text()
m=self.lineEdit_2.text()
然后以h，m替换执行命令中的时，分.
接着就是pushButton的部分了。为pushButton添加监听事件click。
self.pushButton = QtWidgets.QPushButton(shut,clicked=self.sd)
1
self.pushButton=QtWidgets.QPushButton(shut,clicked=self.sd)
其中，self.sd为触发该事件后，需要执行的操作。

运行后，即出现如图操作窗口
#运行效果：
运行shut.py，输入12和53点击set，这时我们查看任务计划：
发现任务已经在计划中。点击Remove，刷新任务计划。
成功移除任务，功能实现
当然这只能在用户安装Python，并安装相关组件前提下才可运行。想要在任何windows使用，则需要下面的操作。
#打包：
笔者打包用的是Python的Pyinstaller组件。cd 到shut.py所在目录后，执行cmd命令:
pyinstaller -w shut.py
1
pyinstaller-wshut.py
这时，在shut.py所在目录生成dist文件夹。生成的exe路径。dist>>shut(Python源码文件名)>>shut.exe.前面顺利的话，双击shut.exe便会显示前面源码运行同样的窗口和操作。这样，你就可以把shut目录整个发给你的朋友。他们就可以通过双击shut.exe使用你的程序了。
至此，关于最近做的windows自动关机小软件的经验叙述完毕~
