Python 3, one class used across multiple modules

问题

I would like to use the following class across multiple modules without needing log = InitLog() in every module. I need to be able to use ONE defined class variable (in this example log) across multiple modules. What is the best way to do this without altering my current code too drastically. Thanks

import os
import sys
import pdb
import fileinput
import Tools


class InitLog:
    def __init__(self):
        pass
    def setLaws(self):
        self.sound = 'off'
        self.engine = 'goo.txt'

    def Update(self):
        while Tools.Locked.State.LogAddress == True: pass
        Tools.Locked.State.LogAddress = True
        try: os.remove(path + '/' + self.dest + '/init.log')
        except: pass

        summery = 'sound: ' + self.sound + '\n'
        summery += 'engine: ' + self.engine + '\n'

        path = os.getcwd()
        if not os.path.exists(self.dest): os.makedirs(self.dest)
        if os.path.isfile(path + '/' + self.dest + '/init.log') == True: os.remove(path + '/' + self.dest + '/init.log')
        with open (path + '/' + self.dest + '/init.log', mode='a', encoding='utf-8') as a_file:
            a_file.write(summery)
        Tools.Locked.State.LogAddress = False


Tools.Locked.State.LogAddress = False
log = InitLog()
log.setLaws()
log.sound = 'on'
log.Update()

Create a module called logging which contains log. In other modules use from logging import log.
