Question

我使用标签来显示我在Tic Tac Toe游戏中获胜的人。但是，当标签被不同的文本覆盖时，其下的旧文本不会被清除，只会被覆盖。因此，一些旧文本有时会通过。有没有办法清除标签来实现这一点，而不只是制作同一地点的不同标签？如果我尝试在标签上使用.destroy()方法，则会出现错误的窗口路径错误。

这是我的代码：

您只需要更新标签中的文字;没有必要为每个游戏重新创建和重新标记标签分数也需要更新。
login: function () { axios.post( this.BASE_URL + "/api/login", { // you must have this here username: this.username, password: this.password, }).then(function(data){ console.log(data); }); },可能有点过分;你可以用self.update()替换它，或者完全删除它。

self.update_idletasks()

如何使用Tkinter清除标签？
