基于Python log 的正确打开方式

import osimport logbookfrom logbook.more import ColorizedStderrHandlerimport smtplibLOG_DIR = os.path.join('log')if not os.path.exists(LOG_DIR):  os.makedirs(LOG_DIR)def get_logger(name='test', file_log=False):  logbook.set_datetime_format('local')  ColorizedStderrHandler(bubble=False).push_application()  if file_log:    logbook.TimedRotatingFileHandler(os.path.join(LOG_DIR, '%s.log' % name), date_format='%Y%m%d', bubble=True).push_application()  return logbook.Logger(name)LOG = get_logger(file_log=True)def send_email(email_conf, message):  smtp = smtplib.SMTP()  smtp.connect(email_conf['host'], email_conf['port'])  smtp.login(email_conf['user'], email_conf['password'])  smtp.sendmail(email_conf['fromaddr'], email_conf['recipients'], message.as_string())

from logger import LOG  if __name__ == "__main__":   LOG.info('Checking %s:%s ...' % (str(date), str(data_type)))
