现在我要做的是：
我想将变量ip_path_field，op_path_field，文件名作为参数传递给名为Scrapper的函数。现在ip_path_field，op_path_field，文件名都是用户输入，而不是硬编码的字符串。现在，每当我运行以下代码时，便会打开GUI，并且每当在所需的编辑框中提供输入内容并按Submit按钮时，都会得到以下未定义的错误名称“ ip_path_field”。这段代码的目的是将用户定义的文件路径传递到上面的代码中定义的名为Scrapper（）的函数。
答案 0 :(得分：3)
您需要创建一个获取值的回调，然后将它们传递给执行工作的函数。
示例：
class GUI:
def __init__(self,master):
...
self.Submit = Button(..., command=self.handle_submit)
...
def handle_submit(self):
ip_path = self.ip_path_field.get()
op_path = self.op_path_field.get()
filename = self.filename.get()
self.Scrapper(ip_path_field,op_path_field,filename)
答案 1 :(得分：0)
您遇到的主要问题与如何构建方法有关。相反，您应该将unsubscribe调用放入该方法中。这样，您可以简单地运行命令来调用scraper，而无需传递参数。我已将您的代码重新编写为更严格地遵循PEP8标准并包括方法更正。
您只需要将Observable前缀应用于类属性/方法。标签/按钮之类的内容在以后的代码中不会被修改，应该留作普通的窗口小部件，而这些窗口小部件未分配为属性。
接下来，我将所有导入内容移到代码的顶部。您只需要一次导入一个库，并且所有库都应列在代码的顶部。请记住，对于导入，最好使用get()而不是使用self.来防止意外覆盖。
我已将您的字符串连接更改为不推荐使用import tkinter as tk的{{1}}方法。
这是您的代码，还进行了一些基本清理。
*所有这些都表示您下次应该尝试使用最少的代码。当您将问题缩小到确切范围时，更容易解决问题。例如，根据您的问题，Minimal, Complete, and Verifiable example看起来像这样。
