Use a format string: cmd = "myscript %s %s %s %s" os.system(cmd % (p1,p2,p3,p4)) OR cmdstr = cmd % p1,p2,p3,p4 os.system(cmdstr) The second form is easier to debug... > to use popen3 to keep track of stdin, stdout, and err, Ok, substitute popen3 for system(). Or better still use the subprocess module and the Popen class. See the OS topic in my tutor for more on the subprocess module.
