使用log记录日志

１　使用log日志：

import logginglogging.basicConfig(level=logging.INFO, filename=＇mylog.log＇)logging.info('start program')print 1/0logging.info('the division succeeded')logging.info('Ending program')

2 使用输入输出流：

import syslog_file = open('/tmp/py.log', 'a')err_file = open('/tmp/py.err', 'a')sys.stdout = log_file;sys.stderr = log_err;print('Hello')
