如何在 Tkinter 中为循环中创建的相同按钮提供唯一名称？

Question

我使用循环在框架内创建了 3 个空白按钮（因此我可以使用尺寸而不是高度和宽度使它们具有精确的大小）在一个更大的框架内，将它们组织成一个网格。这些按钮都显示正常，但稍后在程序中我想单独更改文本，但因为它们没有唯一的名称，我无法使用 config. 下面是按钮创建代码：

frameNames = ["A1", "A2", "A3", "A4", "B1", "B2", "B3", "B4", "C1", "C2", "C3", "C4"]
while buttonNumber <= 11:
        frameN = frameNames[buttonNumber]
        frame = tkinter.Frame(buttonFrame, width=100, height=100)
        frame.rowconfigure(0, weight=1)
        frame.columnconfigure(0, weight=1)
        frame.grid_propagate(0)
        if "A" in frameN:
            frame.grid(row = 0)
        elif "B" in frameN:
            frame.grid(row = 1)
        elif "C" in frameN:
            frame.grid(row = 2)
        if "1" in frameN:
            frame.grid(column = 0)
        elif "2" in frameN:
            frame.grid(column = 1)
        elif "3" in frameN:
            frame.grid(column = 2)
        elif "4" in frameN:
            frame.grid(column = 3)
        frame.grid(padx = 25, pady = 25)
        button = tkinter.Button(frame, text = " ", bg = "Blue").grid(sticky="nsew")
        buttonNumber += 1
    
    window.mainloop()

您可以使用字典来存储创建的按钮并使用单元格位置或名称（来自frameNames）作为键：

frameNames = ["A1", "A2", "A3", "A4", "B1", "B2", "B3", "B4", "C1", "C2", "C3", "C4"]
buttons = {}  # dictionary to hold the buttons
for name in frameNames:
    row = ord(name[0]) - ord("A")
    col = int(name[1]) - 1
    frame = tk.Frame(buttonFrame, width=100, height=100)
    frame.grid(row=row, column=col, padx=25, pady=25)
    btn = tk.Button(frame, bg="blue")
    btn.place(relwidth=1, relheight=1)
    buttons[row,col] = btn  # or buttons[name] = btn

然后您可以使用键 row,col 访问特定按钮，例如buttons[0,0].
