我想對我的 GUI 中的所有按鈕只使用一個功能（self.toggle），而不是為每個按鈕做一個。我試圖只更改沒有數字的 self.button 的名稱，然后我只在一個按鈕上更改了文本，而不是所需的按鈕。有沒有簡單的方法來做一個功能？我只是從 Python 開始。提前致謝。
from tkinter import *
from tkinter.ttk import Button
class Application(Tk):
def __init__(self, *args, **kwargs):
Tk.__init__(self, *args, **kwargs)
self.create_widgets()
self.number = [1, 2, 3]
self.mainloop()
def toggle1(self, number):
if self.button1.config('text')[-1] == f"{number}: ON":
self.button1.config(text=f"{number}: OFF")
print("OFF")
else:
self.button1.config(text=f"{number}: ON")
print("ON")
def toggle2(self, number):
if self.button2.config('text')[-1] == f"{number}: ON":
self.button2.config(text=f"{number}: OFF")
print("OFF")
else:
self.button2.config(text=f"{number}: ON")
print("ON")
def toggle3(self, number):
if self.button3.config('text')[-1] == f"{number}: ON":
self.button3.config(text=f"{number}: OFF")
print("OFF")
else:
self.button3.config(text=f"{number}: ON")
print("ON")

uj5u.com熱心網友回復：
您可以將按鈕小部件傳遞給toggle()如下：
...
class Application(Tk):
...
def toggle(self, button):
number, state = button['text'].split(': ')
state = 'ON' if state == 'OFF' else 'OFF'
button['text'] = f'{number}: {state}'
print(number, state)
def create_widgets(self):
...
self.button1 = Button(self, text="1: OFF", command=lambda: self.toggle(self.button1))
...
self.button2 = Button(self, text="2: OFF", command=lambda: self.toggle(self.button2))
...
self.button3 = Button(self, text="3: OFF", command=lambda: self.toggle(self.button3))
...
