python 在for循环中创建，但不能引用数据

我有一个tkinter项目，最终目标是有一个窗口，其中json文件中的所有数据都显示为单独的对象（一个按钮或一个按钮旁边），然后可以单击这些对象来更改数据并将其保存回json文件，以及添加新级别的选项。
复杂的是，因为我将其设置为“未来证明”，所以我必须在循环中创建按钮，因此它们的名称不会被定义以供以后引用。（），在tkinter中传递它们，v.focus_get（），而且没有一个是正确的。有那么一秒钟我以为。网格（）在同一行上可能会使我引用网格对象，虽然没有错，但改变它并没有解决这个问题。使用cget（）给了我“.”作为我试图拉取的任何信息。
我没有结婚，我的格式，它可以是一个弹出窗口，通过文本框，我只是不想把所有的信息都放在一个列表框中，有人可能会搞砸json格式，我将简化json文件和下面的代码中的数据。

解决：最主要的问题是不命名按钮就不能引用按钮，而且使用tkinter内置的name函数不允许引用。我必须为按钮创建一个类，使用tk.IntVar（）来命名按钮。

import json
import tkinter as tk

#make buttons
class GregButton(tk.Button):
    def __init__(self, window, name="", *args, **kwargs):
        self.name = tk.IntVar()
        self.name.set(name)
        super(GregButton, self).__init__(
            window, *args, textvariable=self.name, command=self.button_do, **kwargs
        )

    def button_do(self):
        print("hello")
        # Top level window
        frame = tk.Tk()
        frame.title("TextBox Input")
        frame.geometry("400x200")
        # Function for getting Input
        # from textbox and printing it
        # at label widget

        def printInput():
            inp = inputtxt.get(1.0, "end-1c")
            lbl.config(text="Provided Input: " + inp)
            self.name.set(inp)

        # TextBox Creation
        inputtxt = tk.Text(frame, height=5, width=20)

        inputtxt.pack()

        # Button Creation
        printButton = tk.Button(frame, text="Print", command=printInput)
        printButton.pack()

        # Label Creation
        lbl = tk.Label(frame, text="")
        lbl.pack()
        frame.mainloop()

# load data from json file
with open("pricing_data.json", "r") as pricing_data_json:
    pricing_data = json.load(pricing_data_json)

#levels
stone_levels = pricing_data["stone_levels"]
#window no frame
window = tk.Tk()
#lsit of buttons for later?
btns = []
#make and add buttons to list
for granite_level in stone_levels:
    btns.append(GregButton(window, stone_levels[granite_level]["Name"]))
#pack buttons onto window
for btn in btns:
    btn.pack()
window.mainloop()
