Execute code when Django starts ONCE only?

Question

I\'m writing a Django Middleware class that I want to execute only once at startup, to initialise some other arbritary code. I\'ve followed the very nice solution posted by

if you want print "hello world" once time when you run server, put print ("hello world") out of class StartupMiddleware

from django.core.exceptions import MiddlewareNotUsed
from django.conf import settings

class StartupMiddleware(object):
    def __init__(self):
        #print "Hello world"
        raise MiddlewareNotUsed('Startup complete')

print "Hello world"
