You should be using the subprocess module to call other executables. subprocess.Popen takes a list as it's first argument. The first item in the list is the executable you'd like to call. All list items are the arguments passed to the executable.

from subprocess import Popen
p = Popen(['/usr/bin/foo', 'arg1', 'arg2'])

Take a look at scons: http://www.scons.org/

The build configuration files you write for it are python scripts.
