Waiting for the Bitwig - send DM to my Twitter account on change

Bitwig.py

#!/usr/bin/env python
import urllib2
import time

class bitwig:
    running = None
    last_size = 0
    
    def __init__(self):
        if not self.running:
            self.running = 1
            while 1 == 1 :
                self.run()
                time.sleep(10) # pause 10 sec
        
    def run(self):
        response = urllib2.urlopen('http://www.bitwig.com/en/bitwig-studio') #target url
        html = response.read()
        sz = len(html)
        print str(sz)
        if sz != self.last_size: # reminder : will send a DM on start up
            print 'from '+ str(self.last_size) + ' to ' + str(sz)
            msg = str(self.last_size) + '-' + str(sz)
            self.last_size = sz
            response = urllib2.urlopen('http://localhost:3000/test/omnimono/'+msg) #local rails app sends me DM in twitter
            
go = bitwig()

To give you an idea of how this would be written in more idiomatic Python:

#!/usr/bin/env python
import urllib2
import time

def check_size():
    return len(urllib2.urlopen('http://www.bitwig.com/en/bitwig-studio').read())

if __name__ == '__main__':
    size = last_size = check_size()
    while True:
        size, last_size = check_size(), size
        if size != last_size:
            urllib2.urlopen('http://localhost:3000/test/omnimono/{}-{}'.format(size, last_size))
        time.sleep(10)

Thx, I wrote this fast and cheap. Much tighter!
