如何在Mac上的Python中从TextEdit中打开文本文件？
问题内容：
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，将数据写入文本文件，然后启动该文本文件以便可以打印。
我该如何实现？
我尝试使用网络浏览器，但是没有运气。
问题答案：
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，因为避免转义问题更加容易：
import subprocess
subprocess.call(['open', '-a', 'TextEdit', file])
