我試著做一個圣誕節倒數計時器，我快完成了。我運行了這段代碼，它運行了一秒鐘，然后關閉了所有內容，沒有錯誤。我在 python 方面不太先進，所以如果我犯了任何愚蠢的錯誤，那就是原因。可能來自執行緒嗎？我對執行緒真的很陌生，所以可能是這樣。
繼承人我的代碼現在。

uj5u.com熱心網友回復：
您不需要在這里使用執行緒。
在 tkinter 中，您可以after()在一段時間后使用方法呼叫函式：
def xm():
# calculations and display
root.after(1000, xm)
button_time = Button(root, text= 'CLICK FOR COUNTDOWN', command = xm, height = 5, width = 20)
button_time.grid(row = 0, column = 0)
root.mainloop()
