Do it this way:

subprocess.call(['/etc/init.d/tomcat6', 'stop'])

or, if you really need to capture the standard output/error

p = subprocess.Popen(['/etc/init.d/tomcat6', 'stop'],
                     stdout=subprocess.PIPE,
                     stderr=subprocess.PIPE)
stdout, stderr = p.communicate()
