Unix commands within Python code

[Kory Wheatley]

Hi all,

I've just started to learn Python and I have a
question.

What is the syntax to embed Unix commands, or call
other programs within a Python script?

for example I would like to use a system chmod unix
command in the python script:

chmod 666 /tmp/filename

or call another script

/home/mailman/bin/list_members facultynews[color=blue]
>${DIR}facultyn ew[/color]

I would appreciate if someone can send me the syntax,
or if its even possible.

Basic is os.system(), but there are also
several os.popen#() calls depending on if you
need to get output or set environment before
execution.

There are also many os. commands that can
do this without shelling out to the Unix
shell, in particular:

os.chmod(path, mode)

There's also the shutil module with some useful shell-like commands.
