Python 如何将两个函数的值相加？(2.0)
正如我昨天承诺的，真正的代码来了 我将编写一个程序，用于定义房间中的混响时间。解释整个项目，花了太多时间。我尝试了建议的方法，但我做错了 在第一页中，有不同声音频率下材料的所有吸收度，在第二页中，用户必须输入面积（平方米）并选择材料。按下OK按钮后，函数getBottomChoice和getWallChoice将PageOne中的材料值乘以用户输入，以获得吸收面积。但不幸的是，它不起作用。我如何打印所选材料的新值吸附面积，仅用于签入？最后但并非最不重要的是，我如何总结所选材料的abs面积并打印出来，按频率列出？提前谢谢Python 如何将两个函数的值相加？(2.0),python,inheritance,tkinter,Python,Inheritance,Tkinter,正如我昨天承诺的，真正的代码来了 我将编写一个程序，用于定义房间中的混响时间。解释整个项目，花了太多时间。我尝试了建议的方法，但我做错了 在第一页中，有不同声音频率下材料的所有吸收度，在第二页中，用户必须输入面积（平方米）并选择材料。按下OK按钮后，函数getBottomChoice和getWallChoice将PageOne中的材料值乘以用户输入，以获得吸收面积。但不幸的是，它不起作用。我如何打印所选材料的新值吸附面积，仅用于签入？最后但并非最不重要的是，我如何总结所选材料的abs面积并打印出

好了，我们的谈话结束了，在评论和一些关于事物如何联系的假设中，我重构了你的代码 让我知道如果有什么不工作，作为仔细检查 4缩进空格为标准。它有助于提高可读性，如果遵循标准，可以避免缩进不匹配等问题 确保您的示例中包含所有导入内容，因为这是一个重要的故障排除步骤，让我们知道可能需要哪些库来测试您的示例 我已经按照PEP8标准重构了您的代码。你有一个混合格式正在进行，没有什么是一致的 从多个类继承可能会很棘手，因此，请改为从框架继承，然后创建一个作为页面实例的类属性 从页面中的属性创建新值的函数的工作方式与预期不同。相反，您将希望对所有内容求和，然后返回该求和值 sumAbsorptionArea方法中的数学无法工作，因为您正在使用对方法的引用，而不是执行这些方法 出于某种原因，在按钮上混合使用命令和绑定，因此在某些函数/方法中必须有一个事件变量。相反，只需使用命令 就个人而言，您使用了很多行来定义属性。我会想办法缩短这个。最好是一个值列表或一个字典在这里工作得很好。不过你可以自己解决这个问题D 重构代码：

我一眼就看到2期。您没有将tkinter作为tk导入，并且您的缩进不正确。这应该是4个空格，因为代码中有很多错误！即使是导入也很混乱——从tkinter import*开始，然后在类中混响timetk.TKYou发布了太多的代码。请创建一个。Stackoverflow不是完整程序的免费调试服务。你需要专注于一个小问题，并包含足够的代码来说明这个问题。@Mike SMT:你提到的这些都不是错误，都是个人偏好。虽然如果他们坚持最佳实践会很好，但这与所问的问题并不相关。@BryanOakley导入是错误的。它们使用tk.tk，但不作为tk导入。他们也在使用messagebox，但也不导入它。首先，我很惊喜你能如此迅速、热情地帮助我。谢谢大家。好的，我看到你使用了另一种策略。在类页面中定义所有变量，而不使用任何方法，因此可以在类页面2中直接更改变量的值。但不幸的是，它不起作用。当我点击底部选择的上方OK按钮时，我得到一个错误。下方的“确定”按钮未连接，如果我单击它，则没有反应。最后，sum_absorption_area-function没有做任何事情：：这里是错误：`File E:/Python/Akustik/Akustik/Test2.py，第185行，在get_bottom_选项返回和[pvc_250，pvc_500，pvc_1000，pvc_2000，pvc_4000]TypeError:不支持+：'int'和'tuple'的操作数类型`Jionny odd。这一错误在我这边没有发生。我想知道元组是从哪里来的。我有个会议要去，但我回来后会再看一眼。告诉我你正在使用什么插补，你期望得到什么，我回来后会看一看。只是想让你们知道，当我按下sum键时，我会在屏幕上打印一个没有错误的值。所以，也许这是你正在使用的某个特定的东西，我需要尝试。现在我在Spyder和Jupyter笔记本中尝试了它，都描述了这个错误：也许我做错了什么。。。好的，待会儿见@Jionny你用的是什么插补？
