Yes

No

Suggestion: make "constant" names upper case e;g; IDLE = 1. This helps 
later when reading code to remind you that IDLE is intended to be constant.

If you
import constants
then you must prefix the module name to each constant:
constants.IDLE

OTOH if you
from constants import *
then just use the constant name.
