封装写日志的类

import logging
from logging import handlers
class MyLogger():
   def __init__(self,file_name,level='info',backCount=5,when='D'):
      logger = logging.getLogger()  # 先实例化一个logger对象，先创建一个办公室
      logger.setLevel(self.get_level(level))  # 设置日志的级别的人
      cl = logging.StreamHandler()  # 负责往控制台输出的人
      bl = handlers.TimedRotatingFileHandler(filename=file_name, when=when, interval=1, backupCount=backCount, encoding='utf-8')
      fmt = logging.Formatter('%(asctime)s - %(pathname)s[line:%(lineno)d] - %(levelname)s: %(message)s')
      cl.setFormatter(fmt)  # 设置控制台输出的日志格式
      bl.setFormatter(fmt)  # 设置文件里面写入的日志格式
      logger.addHandler(cl)
      logger.addHandler(bl)
      self.logger = logger

   def get_level(self,str):
      level = {
         'debug':logging.DEBUG,
         'info':logging.INFO,
         'warn':logging.WARNING,
         'error':logging.ERROR
      }
      str = str.lower()
      return level.get(str)

lw_log = MyLogger('lw.log','debug')
lw_log.logger.warning('哈哈哈')
