¿Cómo abro un archivo de texto en TextEdit de Python en Mac?

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

Estoy escribiendo un progtwig que crea un informe a partir de datos de una base de datos, escribe esos datos en un archivo de texto y luego se supone que debe iniciar ese archivo de texto para poder imprimirlo.

¿Cómo logro esto?

He intentado usar el navegador web, pero no tengo suerte.

Puede usar la utilidad /usr/bin/open OSX:

 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. 

También debe usar el módulo de subprocess lugar de os.system , ya que es mucho más fácil evitar los problemas de escape con él:

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