记录 - 如何对不同的文件使用与 class 相同的记录器？

Question

如何对不同的文件使用与class相同的记录器？

例子：

mylog.py

import logging

class MyLog():
    def __init__(self):
       pass
    def getLogger():
       logger = logging.getLogger(__name__)
       logger.setLevel(logging.INFO)
       ch = logging.StreamHandler()
       ch.setLevel(logging.DEBUG)
       formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
       ch.setFormatter(formatter)
       logger.addHandler(ch)
       logger.addHandler(file)
    
    #etc list of formatting that I want to be the same for all the files using this class

如何为此文件调用相同的记录器？ （我猜我需要传递文件名而不是使用 name__）

myfile.py

import mylog

logger = mylog.MyLog() #? how can I get correctly the logger from the other file? 

logger.info("Test Message") #I want this logger info to use the formatting specified in mylog.py

除了定义之外，模块还可以包含成员变量。 所以你可以这样做（或多或少）：

mylog.py

import logging

def getLogger():
   logger = logging.getLogger(__name__)
   logger.setLevel(logging.INFO)
   ch = logging.StreamHandler()
   ch.setLevel(logging.DEBUG)
   formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
   ch.setFormatter(formatter)
   logger.addHandler(ch)
   logger.addHandler(file)

#etc list of formatting that I want to be the same for all the files using this class
   return logger

logger = getlogger()

myfile.py

from mylog import logger

logger.info("Test Message") #I want this logger info to use the formatting specified in mylog.py
