我正在嘗試學習如何執行緒使用tkinter和遇到問題。我的主要計劃是最終打開一個程式并使用熱鍵瀏覽所述程式的選單，以自動執行我正在執行的遞回程序。我知道這不是最有效的方法，但有理由說明為什么這是唯一可用的方法。
我現在正在嘗試簡單地撰寫一個記事本版本的代碼，該代碼將復制文本框用戶輸入字串并將它們輸入到記事本中。我聽說我需要使用執行緒來完成我的最終專案，但顯然我沒有做正確的事情，因為一旦記事本打開程式就不會繼續。下面是代碼：

uj5u.com熱心網友回復：
subprocess.call
是一個阻塞功能，因為它等待它完成，在這種情況下意味著它會等到您關閉記事本，然后再繼續自動化。
你可能想用
subprocess.Popen
因為它在新行程中執行子程式，這意味著它將打開記事本，然后繼續自動化。
對于您的情況，您實際上只需要更改call為Popen，這實際上是唯一需要的更改。
有用：
subprocess.Popen檔案
