Python: changing a process name with setproctitle

I have a python script that runs a number of C ++ programs, a command line parameter is passed to each program, as shown below

process_path "~/test/"
process_name "test"
num_process = 10

for p in range(1, num_processes, 1):
    subprocess.Popen([process_path + process_name, str(p)], shell = False)

Is it possible to set setproctitle to rename each of these processes so that I can include the command line parameter as part of the process name, if so, how would you do it?

If you pass kwarg executableto subprocess.Popen, you can use the first argument in the argument list:

subprocess.Popen(['some string you choose', str(p)],
                 executable=process_path+process_name, shell=False)

docs say: "On Unix, it becomes the display name for the executable in utilities such as ps."
