我有一個程式，功能就是給選定檔案夾里的檔案重命名。
現在想添加一個功能，能夠動態顯示處理完了幾個檔案。
代碼如下：

運行后，下面的Label始終無顯示，請問如何修改？
uj5u.com熱心網友回復：
這一行self.value.trace("r", self.show_result)
你要改成
self.value.trace("w", self.show_result)

改了，還是有問題。我想可能需要加一個執行緒，但是問題仍然存在。

我運行了，還是沒有看到最后一行 file(s) renamed前面數字的變化（假設檔案夾有3個檔案，直接就顯示成3了，沒有看到1、2）uj5u.com熱心網友回復：
按你的需求，加個定時器比較方便，設定了固定的時間間隔或者這里可以根據檔案數量設定了這個值，3.0/檔案數，表示不管檔案多少，數字切換顯示總時長大約3秒，免得檔案多的時間等待時間過長

我這樣改了一下，成功了。執行緒啟動的時機影響很大：在點擊按鈕就啟動執行緒，和點擊按鈕喚起rename再啟動執行緒，這兩者差得太遠了。雖然我不太理解為什么會造成這么大的差異。
