You can use below script to list all running services,(Windows XP OS not supported)
import subprocess;
process=subprocess.Popen(['wmic','service','get','caption,','name,','state'],stdout=subprocess.PIPE);
for line in iter(process.stdout.readline,''):
print line.rstrip();
Note: Please refer attach text file for script text without indentation error.
sample output would be as below,
running_services.txt (196 Bytes)
