python的gui界面小程序点击按钮闪退

Question

python让用designer设计gui可视化小程序，往里面填充代码。要求是出十道20以内加减法。我的框架运行没有问题，自己编的函数不知道为什么摁按钮就关窗口，运行不了。但是写了槽函数了，不明白为啥。

用代码块功能插入代码，请勿粘贴截图

另一个文件的主函数是
import sys
from PyQt5.QtWidgets import QApplication, QMainWindow
from c01 import *

class MyWindow(QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
        super(MyWindow, self).__init__(parent)
        self.setupUi(self)


if __name__ == '__main__':
    app = QApplication(sys.argv)
    myWin = MyWindow()
    myWin.show()
    sys.exit(app.exec_())

运行结果及报错内容
