Encapsulate Pythons logging module and import it directly for use

The following code implements the logging The logging module is repackaged so that logging can be realized through simple parameter transmission 、 But the file size limit and the number of files stored . And will automatically format the file timestamp

myLogger.py

from datetime import datetime
import logging
from logging.handlers import RotatingFileHandler
import os
def getInstance(fileName=None, fileSize=1024*1024, maxNums=10):
logger = logging.getLogger()
basePath = "logs/" + str(datetime.today().date())
if not os.path.exists(basePath):
os.makedirs(basePath)
fileName = f"{
basePath}/{
'log' if fileName is None else fileName}"
fileName += str(datetime.now().strftime("%H%M%S")) + ".log"
# log File handle settings 
# logFileHandler = logging.FileHandler(fileName, mode="a")
fmt = '%(asctime)s %(filename)s:%(lineno)s %(levelname)s\t - %(message)s'
formatter = logging.Formatter(fmt)
# logFileHandler.setFormatter(formatter)
# log File size and time settings 
logFileRotateHandler = RotatingFileHandler(fileName, "a", fileSize, maxNums)
logFileRotateHandler.setFormatter(formatter)
logger.addHandler(logFileRotateHandler)
# logger.addHandler(logFileHandler)
logger.setLevel(logging.INFO)
logger.info("")
logger.info("******************************")
logger.info("init log: " + str(fileName))
return logger

Use of document module

import myLogger
logger = myLogger.getInstance("log-warn")
logger.warn("hello wan log")
