good security practice says should minimize time @ elevated privilege. 1 way put commands run root in different file , cause file run root. have several options:

1. your script run other script sudo:
   subprocess.check_call(['sudo', '/we/run/as/root']);
2. you make script 'setuid-root' , run it, no sudo needed:
   subprocess.check_call(['/we/run/as/root']);
   (however, on many systems not work because setuid-root disabled on scripts)
3. like #2 use small c-program setuid-root , runs script:
   subprocess.check_call(['/the/c/program']); c-program is:
   int main(void) { return system("/we/run/as/root"); }
