我正在使用tkinter创建一个查看元数据的工具。它的用户将查看当前与许多数据集相关联的元数据，并权衡元数据是否适合数据集。每个数据集必须有自己的窗口。我有一个粗略的布局，但我很难为True/False函数编写函数。

    print(name)

def btn_true(status, i):
    if status == "off":
        true_button.configure(relief=SUNKEN, bg="#D4D5D3")
        false_button.configure(relief=RAISED, bg="#EDEDED")
        status = "on"

def btn_false(status, i):
    if status == "off":
        true_button.configure(relief=RAISED, bg="#EDEDED")
        false_button.configure(relief=SUNKEN, bg="#D4D5D3")
        status = "on"
