Python tkinter井字棋重置棋盘后误报获胜问题求助

你遇到的重置后误判获胜的问题，根源出在reset函数的列表清空逻辑错误：
原代码中遍历clicked列表时，给临时循环变量element赋值为空格，并没有修改原clicked列表的实际元素，上一局的获胜状态一直残留在列表中，因此新局开始后检测逻辑会直接判定符合获胜条件弹出提示。

• 修正clicked列表清空逻辑：将reset函数中原有的无效遍历赋值，替换为通过索引直接修改原列表的每个元素
• 新增平局判定逻辑：当所有格子都被填满且无人获胜时，弹出平局提示并重置游戏
• 规范消息框标题显示，新增回合数重置逻辑，避免新局先后手顺序错乱
• 适配中文提示内容，优化使用体验
