问题描述
我正在使用 python 创建一个 tkinter GUI 来询问问题列表（存储在 excel 中），并计划将所选按钮的结果保存在 .csv 中以提取到 PBI 仪表板中。但是，我在两件事上遇到了困难：1）遍历问题列表，以及 2）创建一个“下一个”按钮来导航到下一个问题（链接到我的第一个问题）。我是 python/Tkinter 的新手，所以任何建议/建议表示赞赏。

解决方法
您可以在创建此标签后更改标签的 text or other standard options。
在此示例中，我正在操作与按钮（响应）关联的变量的值。
Radiobuttons 也有 select() 和 deselect() 之类的命令。
from tkinter import *
from tkinter import ttk
# from openpyxl.workbook import Workbook
# from openpyxl import load_workbook
# initiate variables

global response

}
# prepared question lists
questions = {"governance": ['A','B'],"eligibility": ['C','D'],"operations": ['E','F'],"monitoring": ['G','H'],"continuing_improvement": ['I','J']
}
# initiate the main window
root1 = Tk()
# create main window label
label1 = Label(root1,text="Question Tool")
# add the lable to the root window
label1.pack()
# define exit button

# do something if no answer is selected

# update answers
answers[label_obj_name].append({label_obj["text"]: user_choice})
# check if we have run out of questions

# clear parent tab

# optional: reset response for new tab

# The questions must be different or not repeated in the same category.
# get the next question in the list
