所以問題是在使用第二個視窗時（您使用下一頁按鈕導航到該視窗）。當我在每個框中輸入 8 位二進制數時，前提是它應該將它們加在一起并顯示在標記的添加二進制框中。但目前它似乎沒有正確設定值來執行此操作，它只是在命令列中列印我設定的內容，這表明該方法正在運行。
任何有關如何解決此問題的見解將不勝感激。僅供參考，是的，它是故意為 8 位二進制完成的，是的，它需要使用嵌套類。因為這就是作業需要使用的東西。
對不起，如果這只是一個小錯誤，我在某個地方很笨拙，但我已經被難住了一段時間。
這是修改后的最小可重現示例：

uj5u.com熱心網友回復：
主要問題：要創建第二個視窗，您應該使用Toplevel()而不是Tk().
當我使用Toplevel它時，它會在視窗中顯示文本。
如果您只想看到一個視窗，那么您應該首先看到destroy()舊視窗，然后您可以使用Tk()創建新視窗（使用 new mainloop()）。
但這可能會產生其他問題。它會洗掉視窗中的所有值，當您回傳某個視窗時，它將沒有舊值。創建兩個并在不破壞它們的情況下Frames替換它們可能會更好-它們將保留舊值。Tk()
剩下的只是建議如何創建更具可讀性的代碼：
- 不要放在
SecondWindow里面MainWindow - 不要使用
self2 - 用于
lower_case_names函式和變數
PEP 8中的更多內容——Python 代碼樣式指南
有一些變化的代碼。
它顯示值（我還添加.zfill(8)了顯示8位）
但這會在您每次更改視窗時創建新視窗 -next或者previous- 所以您可能有兩個主視窗等。它需要更多更改。
