如何從Mac上的Python中的TextEdit中打開文本文件？

Question

else: 
    tkMessageBox.showinfo('Report Created', 'Your report was sucessfully created') 
    file = 'Student Report.txt' 
    os.system('TextEdit'+file) 

我正在編寫一個程序，它根據數據庫中的數據創建報告，將該數據寫入文本文件，然後應該啓動該文本文件以便打印。

我該如何做到這一點？

我試圖使用webbrowser，但沒有運氣。

可以使用/usr/bin/open OSX實用程序：

NAME 
    open -- open files and directories 

SYNOPSIS 
    open [-e] [-t] [-f] [-F] [-W] [-R] [-n] [-g] [-h] [-b bundle_identifier] [-a application] file ... [--args arg1 ...] 

DESCRIPTION 
    The open command opens a file (or a directory or URL), just as if you had double-clicked the file's icon. If no application name is specified, the default application as deter- 
    mined via LaunchServices is used to open the specified files. 

    If the file is in the form of a URL, the file will be opened as a URL. 

    You can specify one or more file names (or pathnames), which are interpreted relative to the shell or Terminal window's current working directory. For example, the following com- 
    mand would open all Word files in the current working directory: 

    open *.doc 

    Opened applications inherit environment variables just as if you had launched the application directly through its full path. This behavior was also present in Tiger. 

你也應該使用subprocess module，而不是os.system，因爲它是很容易避免其逃避的問題：

import subprocess 
subprocess.call(['open', '-a', 'TextEdit', file])
