如何在Tkinter中为循环中创建的相同按钮提供唯一的名称

Question

我使用了一个循环在一个更大的框架内创建了3个空白按钮(这样我就可以使用尺寸而不是高度和宽度使它们具有精确的大小(，该框架将它们组织成网格。这些按钮都显示正常，但稍后在程序中我想单独更改文本，但由于它们没有唯一的名称，我无法使用config。这是按钮创建代码：

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()

如果你需要更多信息，请告诉我感谢

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(作为关键字：

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]。
