UI文件的编译
将.UI文件编译为.PY文件(CMD命令行中)：
pyuic5 xxx.ui -o xxx.py
#不可以存在中文！打开编译后的.py文件，新建SLOT()函数并修改连接函数：

在末尾添加运行代码：
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
