Python 3，在多个模块中使用的一类 [英] Python 3, one class used across multiple modules

问题描述

我想在多个模块中使用以下类，而无需在每个模块中使用 log = InitLog（）。我需要能够在多个模块中使用一个定义的类变量（在本示例中为 log ）。在不彻底更改当前代码的情况下，最好的方法是什么。谢谢

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()

推荐答案

创建一个名为 logging 的模块，其中包含 log 。在其他模块中，使用来自日志导入日志。

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