    self.sellamountsetting.resize(70, 20)
    self.sellamountsetting.setText('11')

    print(self.buyamountsetting.text())

    test = self.buyamountsetting.text() + self.sellamountsetting.text()
    print(test)




if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    mainWin = MainWindow()
    mainWin.show()
    sys.exit(app.exec_())

调用QLineEdit.text()会将QLineEdit中的文本作为字符串返回。您必须将其转换为int才能将它们添加到一起。

尝试：

test = int(self.buyamountsetting.text()) + int(self.sellamountsetting.text())
