Python Can'；我不能让代数（二次公式）起作用

我一直在为一门计算机科学课程做一个非常简单的计算器，它有一些函数，计算器的函数是解二次方程。我已尝试使其工作，但出现以下错误：。我不明白为什么它会这样做，因为我输入了所有的内容。。如果有人能帮忙，那就太好了

    label_result.config(text="Result is %d" % result)
    return

在下面添加以下代码

sqrt\u result=partial（..）

：

然后它应该像其他人一样工作。

发布代码，而不是屏幕截图。代码在那里，看起来您缺少部分定义：

algebraMode=partial（albegraMode，labelResult，number1，number2，number3）

谢谢您的回答。我觉得有点傻，因为我没有看到那个哈哈。

algebraMode = partial(algebraMode, labelResult, number1, number2, number3)
