我正在使用標籤來顯示在我製作的Tic Tac Toe遊戲中獲勝者。但是，當標籤被不同文本覆蓋時，其下的舊文本不會被清除，只會被覆蓋。所以，一些舊文本有時會通過。有沒有一種方法可以清除標籤來完成此操作，而不需要在同一個位置製作不同的標籤？如果我嘗試在標籤上使用.destroy()方法，則會出現錯誤的窗口路徑錯誤。如何使用Tkinter清除標籤？
這裏是我的代碼：

配置更新文本，但它覆蓋舊的標籤。更新功能是否清除舊的功能？ – stew3254
我想我只是很困惑這是什麼。增加一個是有幫助的，所以非常感謝。但是，self.update（）沒有幫助。我真的不明白它要做什麼。你能解釋一下嗎？ – stew3254
