没什么好说的,只能说英语好,就是无敌。
以后每天背500个单词。

重点代码

self.pushButton_plus.clicked.connect(self.add) # 绑定事件
def add(self):
        fnum = int(self.lineEdit_first.text()) #lineEdit.text()获取输入文本框的内容,字符串类型
        secnum = int(self.lineEdit_second.text())
        result = fnum + secnum
        self.label_result.setText(f"Addition: {result}")

    def min(self):
        fnum = int(self.lineEdit_first.text()) #lineEdit.text()获取输入文本框的内容,字符串类型
        secnum = int(self.lineEdit_second.text())
        result = fnum - secnum
        self.label_result.setText(f"Minus: {result}")

    def mul(self):
        fnum = int(self.lineEdit_first.text()) #lineEdit.text()获取输入文本框的内容,字符串类型
        secnum = int(self.lineEdit_second.text())
        result = fnum * secnum
        self.label_result.setText(f"Multiply: {result}")

    def div(self):

        secnum = int(self.lineEdit_second.text())
