Python Logging文件子程序

import loggingimport os#   name = log文件里开头显示的名字#   log_file = 你保存的文件名字 例如 Ex.log#   log_path设置你的保存路径#   level 设置保存日志的级别def setup_logger(name='default_logger', log_file=None, log_path='logs', level=logging.INFO):    logger = logging.getLogger(name)    logger.setLevel(level)
    formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
    if log_file:        if not os.path.exists(log_path):            os.makedirs(log_path)        file_handler = logging.FileHandler(os.path.join(log_path, log_file))        file_handler.setFormatter(formatter)        logger.addHandler(file_handler)    else:        stream_handler = logging.StreamHandler()        stream_handler.setFormatter(formatter)        logger.addHandler(stream_handler)
    return logger# example# Cpath="C:Users/xutong/Desktop/"# AElog=Elog.setup_logger('XutongFile','Test.log',Cpath)# AElog.info(i)
