使用日志的六个步骤：
|
|||
|
|
①定义lgger日志器（谁来产生日志，默认是root）: lg = logging.getLogger( 'abc' )
|
|||
|
|
②设置日志等级: lg.setLevel( logging.INFO )
|
|||
|
|
③定义handlers（产生的日志输出到哪里，到控制台还是文件）: con_hand = logging.StreamHandler()
|
|||
|
|
④定义formatter日志打印格式，并绑定handlers
|
|||
|
|
con_hand = logging.StreamHandler() # ③定义handlers（产生的日志输出到哪里，到控制台还是文件）
|
|||
|
|
formatter = logging.Formatter( '%(asctime)s - %(name)s - %(levelname)s - %(message)s'
|
|||
|
|
,datefmt='%Y-%m-%d %H:%M:%S' # 定义时间的格式
|
|||
|
|
) # ④定义formatter日志打印格式，并绑定handlers
|
|||
|
|
con_hand.setFormatter( formatter ) # 并绑定handlers
|
|||
|
|
⑤将handlers的处理添加到日志器进行记录
|
|||
|
|
lg.addHandler( con_hand )
|
|||
|
|
⑥打印日志测试
|
|||
|
|
lg.info('xxxx')
|
|||
|
|
lg.debug('xxx')
