How to run a dos executable from python

[lblr33]

I have an executable (e.g. myprog.exe) which takes some set number of
arguments.

This command works ok:
os.system(r"c:\tmp\myprog.exe arg1 arg2 arg3")

The problem is that the path to the program and the arguments are
variable at runtime so I need to pass them as arguments.

Thanks

alternatively, you could use the subprocess module instead of os.system,
and pass

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

retcode = subprocess.call(["c:/tmp/mycmd.exe", arg1, arg2, arg3])

Take a look at the subprocess module or on older versions of Python
you can use os.spawn.
