python日志模块

python的日志模块使用logging，如果想要输出符合自己的预期，需要重新定义，废话不多说，直接贴代码。

# encoding: utf -8
from logging.handlers import TimedRotatingFileHandler
import logging
import os
import inspect

#调用方法log.debug('logname.log','输出内容')
this_file = inspect.getfile(inspect.currentframe())
path = os.path.abspath(os.path.dirname(this_file))
class log:
    def __init__(self):
        if os.path.isdir('%s\log'%path):  #创建log文件夹
            pass
        else:
            os.mkdir('%s\log'%path)

    def debug(self,logname,kwarg):
        logFilePath = '%s\log\%s'%(path,logname)
        logger = logging.getLogger("yourName")
        logger.setLevel(logging.DEBUG)
        handler = TimedRotatingFileHandler(logFilePath,
                                           when="midnight",
                                           interval=1,
                                           backupCount=20)
        formatter = logging.Formatter('%(asctime)s   %(levelname)s  %(message)s')
        handler.setFormatter(formatter)
        logger.addHandler(handler)
        logger.debug('%s'%(kwarg))
        logger.removeHandler(handler)

    def error(self,logname,kwarg):
        logFilePath = '%s\log\%s'%(path,logname)
        logger = logging.getLogger("yourName")
        logger.setLevel(logging.ERROR)
        handler = TimedRotatingFileHandler(logFilePath,
                                           when="midnight",
                                           interval=1,
                                           backupCount=20)
        formatter = logging.Formatter('%(asctime)s   %(levelname)s  %(message)s')
        handler.setFormatter(formatter)
        logger.addHandler(handler)
        logger.error('%s'%(kwarg))
        logger.removeHandler(handler)

handler = TimedRotatingFileHandler(logFilePath, when="midnight", interval=1, backupCount=20) 定义写入日志的策略：

1.每天一个日志文件。

2.超过20个，删除最早生成的日志。

formatter = logging.Formatter('%(asctime)s %(levelname)s %(message)s') 定义日志输出的格式

log().debug('test.log','Hello World...')

 日志输出：
