python中logging模块的使用

import logging
import time

import re

#os.listdir删除文件
def rmFile(path):
    files = os.listdir(path)
    for file in files:
        file_path = os.path.join(path, file)
        if os.path.isfile(file_path):

                os.remove(file_path)
            except:
                print("except: 删除%s" % file_path)

#日志输出部分
def comnLogger(logfile):
    handler = logging.FileHandler(logfile, mode="w", encoding="utf-8")
    myformat = "%(asctime)s %(filename)s [line:%(lineno)d]:%(levelname)s %(message)s"
    formatter = logging.Formatter(myformat)
    handler.setFormatter(formatter)
    mylogger = logging.getLogger("logs")
    mylogger.addHandler(handler)
    mylogger.setLevel(logging.DEBUG)
    return mylogger

#创建日志存放目录
logdir = r"C:UsersshtangDesktopxingBaKeSync" 
if not os.path.isdir(logdir):
    os.makedirs(logdir)
#清空logdir下的文件
rmFile(logdir)
#定义日志输出文件
logname = "log_" + time.strftime("%Y%m%d_%H%M%S",time.localtime()) + ".txt"
logfile = os.path.join(logdir,logname)
#定义一个公共的logger
mylogger = comnLogger(logfile)

#覆写print方法
def print(message):
    mylogger.info(message)
    rpa.logger.info(message)
