我是tkinter的新手，我有3個標題窗口。 如果我從窗口1到窗口2去，focus_set工作，並 如果我從窗口2到window3，focus_set工作， 如果我回來從window3到窗口2，其重點不在於進入文本，這是我想重點。Python tkinter focus_set SubMenu後點擊返回按鈕
它的工作從window2到window1。 我的簡單代碼如下：我知道它有點多的代碼，但它會幫助找到確切的錯誤。
我嘗試過發現錯誤，無法工作。

錯誤是：我知道錯誤的類型，但我想具體的代碼，在那裏我需要改變
Attribute Error: 'str' object has no attribute focus_set
你必須在阻止它運行代碼不平衡報價。 –
您還需要格式化您的代碼以匹配縮進。 – Khristos
