from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_MainWindow(QtWidgets.QMainWindow):
    def __init__(self):
        super(Ui_MainWindow,self).__init__()
        self.setupUi(self)
        self.retranslateUi(self)
        self.set_myUi()
    def setupUi(self, MainWindow):
		根据自己的界面，使用PYUIC会自动生成这个函数
    def set_myUi(self):
        # 这里的start_btn是你要点击的Button名字(ui里确定了)，pushButton_start是触发函数
        self.start_btn.clicked.connect(self.pushButton_start)
    def pushButton_start(self):
		# 根据需求，个性化选择后续操作
