問題描述

我想使用 asksaveasfilename 對話框將我在 Text 小部件中輸入的一些內容保存為 .txt 或 .doc 格式.在此之后，我希望它分別打開.記事本或 MS Word.

I want to save some stuff I entered in a Text widget to a .txt or .doc format, using an asksaveasfilename dialog box. After this I want it to open in resp. Notepad or MS Word.

from tkFileDialog import asksaveasfilename
import os.path

name = asksaveasfilename(
           initialdir="dir",
           title="Save as",
           filetypes=[("Text files",".txt"),("Word files",".doc")])

data = open(name,"w")
data.write("text from text widget")

os.startfile(name)

它會創建文件，但不會在 MS Word 或記事本中打開它.相反，它詢問我想如何打開這個文件.如果我選擇程序，它將正確打開，但我希望它直接打開.(不選擇打開文件的程序).當我直接在文件名:"框中提供擴展名時，它會按照我想要的方式工作.

It creates the file but it won't open it in MS Word or Notepad. Instead it asks how I want to open this file. If I choose the programm it will open correctly, but I want it to open directly. (without choosing a program to open the file with). When I give the extension directly in the "File name:" box it works the way I want though.

這有效:文件名:something.doc保存類型:Word 文件 (*.doc)---> 創建 something.doc 并在 MS Word 中打開它.

This works: File name: something.doc Save as type: Word file (*.doc) ---> creates something.doc and opens it in MS Word.

但這并不文件名稱:某事保存類型:Word 文件 (*.doc)---> 創建一些東西(沒有擴展名)并詢問我希望它在什么程序中打開.

But this doesn't File name: something Save as type: Word file (*.doc) ---> creates something (no extension) and ask in what program I want it to open.

我使用 Python 2.7.8、Windows 8、Office 2010.

推薦答案

加上print name就可以看到問題，例如

You can see the problem if you add print name, e.g.

C:/Users/jsharpe/Downloads/testing

請注意，沒有添加任何擴展 - 我只輸入了 "testing".filetypes 參數對于限制用戶選擇現有文件更有用，如果用戶不提供擴展名，它將不會添加適當的擴展名.

note that no extension has been added - I only entered "testing". The filetypes argument is more useful for limiting the user's selection of existing files, it won't add the appropriate extension if the user doesn't supply one.

您可以為用戶不輸入擴展名的情況設置 defaultextension，但這不會反映在下拉列表中選擇的類型(例如，如果您設置了 defaultextension=".txt" 即使用戶從 filetypes 中選擇該選項，它也不會是 .doc).

You can set a defaultextension for the cases where the user doesn't enter an extension, but this won't reflect the type selected in the drop-down (e.g. if you set defaultextension=".txt" it won't be .doc even if the user chooses that option from filetypes).

name = asksaveasfilename(defaultextension=".txt",
                         filetypes=[("Text files",".txt"),
                                    ("Word files",".doc")],
                         initialdir="dir",
                         title="Save as")

(請注意，隨著您添加越來越多的選項，按字母順序排列的參數順序會讓生活變得更輕松)

附帶說明，您(仍然！)不要 close 文件，這可能會導致問題 - 我建議對文件使用 with 上下文管理器處理:

On a side note, you (still!) don't close the file, which could cause issues - I'd suggest using the with context manager for file handling:

with open(name, "w") as data:
    data.write("text from text widget")
