如何从 Mac 上的 Python 在 TextEdit 中打开文本文件？

Question

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

我正在编写一个程序，该程序从数据库中的数据创建报告，将该数据写入文本文件，然后应该启动该文本文件以便可以打印。

我如何实现这一目标？

我曾尝试使用网络浏览器，但没有成功。

您可以使用/usr/bin/openOSX 实用程序：

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.

您还应该使用subprocess模块而不是os.system，因为使用它更容易避免逃避问题：

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