Exeucte a system command in python script

[ken.carlino@gmail.com]

Hi,

I would like to execute a shell command like this in python:
cmd = 'ant release -Dbuild=build_pr oxyonly -Drev=5.1.130f
-Dprops=\"-MIDP20_LARGE;PU SH_FEATURE=fals e;MIDlet-Version=5.0;ver sion=5.0;MIDlet-Icon=midicon15x 15.png;-FOUR_WAY_NAV_FE ATURE\"
-DThree_Branding =true'

Which of the execl command described here should I use?

http://pydoc.org/1.6/os.html

Thank you for any help.

None. You should use the subprocess module in 2.4 (I really do hope that you're
not using 1.6).

http://docs.python.org/lib/module-subprocess.html

It also works in Pythons as old as 2.2, but you'll have to install it
separately. The website for the separate release is down at the moment, but when
it comes back up:

Almost certainly you are doing something like this:

import subprocess
call(['something', 'or', 'other'])

You need to learn how imports work in Python. Please read the tutorial:

separately.

Among other things you are missing the traceback that the Python
interpreter provides with its error messages. This will point you to a
particular line of the source. If you include a few lines of the source
around that point, as well as a pasted copy of the traceback, we have
some chance to determine the error without overtaxing our psychic powers.
