I don't use service for my own python applications, even standalone
py2exe applications.
I use the Windows taskscheduler that start it once and try every
minute to start it again
but is is running all the time, and the the scheduler does nothing and
wait to see for the next minute.
When the python program crash then the scheduler restart it in the

look here how I do with tcpproxyreflector:

In My MKSBackup
I have a install() function that create the task in the scheduler for
XP and Windows2008

And this code, use a 2 min interval

        print 'create task %s in scheduler' % (task_name, )
        interval=raw_input_with_default('Enter interval in minutes',
'>', str(interval_in_minutes))
        cmd='"%s" -c "%s"' % (os.path.join(install_target,
os.path.basename(sys.argv[0])), os.path.join(target, ini_file))
        schtasks_cmd=[ 'SCHTASKS', '/Create', '/SC', 'MINUTE', '/MO',
interval, '/TN', task_name, '/RU', os.getenv('USERNAME'), '/TR', cmd ]
        if sys.getwindowsversion()[0]>5:
            # under 2008 ? require HIGHEST privilege
            # schtasks_cmd.insert(2, 'HIGHEST')
            # schtasks_cmd.insert(2, '/RL')
            # under 2008, to force the system to ask for the password,
set empty password
            schtasks_cmd.insert(i, '')
            schtasks_cmd.insert(i, '/RP')

Mix all 3 source to get what you want.

Services are probably fine too, but this is another story.
