我正在做的这个项目有点麻烦。我的项目就是这个gui应用程序。在test.py文件中，我调用另一个文件，该文件包含另一个gui窗口的说明。这就是我遇到麻烦的地方。在test.py文件中，如果单击“运行”，将出现一个小窗口。在小窗口中单击测试。如果在窗口的文本字段中输入数字，然后单击enter，则会出现另一个包含文本字段的窗口。我的ide会收到这些错误消息。它说“valueerror:无法将字符串转换为float:”“”我的问题是如何修复此问题，以避免收到此错误消息？它应该打印输入到窗口中的输入。我有两个文件，test.py和model_objects.py。如果您单独运行model_objects.py，它将非常有效。但是，当我尝试将此文件导入test.py时，它不想正常工作。这是用python编程的。此外，我的model_objects.py文件位于项目中名为util的文件夹中。我输入的值是浮点值。我在这方面遇到了麻烦。如果你能帮忙，我将不胜感激。
这是我的密码：
model_objects.py（位于项目中名为util的文件夹中）
