我使用 Python 和 Tkinter 完成了翻譯程式的撰寫。我使用了自動翻譯，沒有按鈕，因此，應用程式變慢了很多。有什么方法可以優化或加快翻譯程序？如果您有任何建議，我很樂意傾聽，但我是 Python 新手。 而且我也對這個問題感興趣，是否可以更改組合框內的文本？

有什么方法可以優化或加快翻譯程序？
您不應該在用戶每次按下按鍵時都嘗試進行翻譯。由于翻譯需要幾百毫秒，您應該等到用戶停止輸入，這樣您就不會在每個字符之間強制停頓。
您可以使用 tkinter 的after方法來安排翻譯在未來發生。每次發布密鑰時，您都可以取消和重新安排翻譯。如果用戶停止輸入一兩秒鐘，翻譯就會發生。
我無法運行您的代碼，但這里是該技術的簡要說明：
import tkinter as tk
import googletrans
after_id = None
translator = googletrans.Translator()
def do_translation():
source = input_text.get("1.0", "end").strip()
translated = translator.translate(source, dest="it")
output_text.delete("1.0", "end")
output_text.insert("end", translated.text)
def schedule_translation(event):
global after_id
if after_id is not None:
event.widget.after_cancel(after_id)
after_id = event.widget.after(1000, do_translation)
root = tk.Tk()
input_text = tk.Text(root)
output_text = tk.Text(root)
input_text.pack(side="left", fill="both", expand=True)
output_text.pack(side="left", fill="both", expand=True)
input_text.bind("<Any-KeyRelease>", schedule_translation)
root.mainloop()
對于更健壯的解決方案，您可以在單獨的執行緒或行程中進行轉換，但多執行緒和多處理會增加很多復雜性。
