从 tkinter 调用变量路径

Question

我正在Python中运行一个代码，它分为两部分，第一个部分是在页面上执行网页抓取的函数，第二个部分是使用tkinter打开一个界面，供用户选择一个包含信息的文件夹已保存。 问题是我无法将用户选择的路径传递给我的网络抓取代码。你能帮我解决这个问题吗？

import tkinter
from tkinter import messagebox,ttk
from tkinter.filedialog import askdirectory
from tkinter.filedialog import FileDialog

botao_executa = ttk.Button(root, text="Executar",command= lambda: geraarquivos())
botao_executa.place(x=10,y=100)



root.mainloop()

例如，我需要将第 84 行返回的路径应用到第 36 行和第 64 行

我尝试生成新函数来存储变量并更改字段的顺序

Answer 1

根据给出的代码简单回答？只需向您的

geraarquivos

函数添加一个默认参数，并将路径传递给您用于按钮命令的 lambda -

lambda: geraarquivos(pasta_label.cget('text'))

。
