有什么方法可以优化代码以加快工作速度吗？

Question

我使用 Python 和 Tkinter 完成了翻译程序的编写。我使用了自动翻译，没有按钮，因此，应用程序变慢了很多。有什么方法可以优化或加快翻译过程吗？如果您有任何建议，我很乐意倾听，但我是 Python 的新手。 And I'm also interested in the question, is it possible to change the text inside the combobox?

Is there any way to optimize or speed up the translation process?

您不应该在用户每次按键时都尝试进行翻译。由于翻译需要超过几百毫秒，您应该等到用户停止输入，这样您就不会在每个字符之间强制暂停。

您可以使用 tkinter 的 after 方法安排翻译在将来发生。每次按键释放时，您都可以取消和重新安排翻译。如果用户停止打字一两秒钟，就会进行翻译。

我无法运行你的代码，但这里是该技术的简要说明：

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()

要获得更强大的解决方案，您可以在单独的线程或进程中进行转换，但多线程和多处理会增加很多复杂性。
