1.1 日誌級別
import logging
"""
logging is filtered by division of information into different levels
DEBUG is the Basic level, While the CRITICAL is the highest level
"""
# logging.basicConfig(level=logging.DEBUG)
# logging.basicConfig(level=logging.INFO)
""" The output will be same, if WARN replace WARNING """
# logging.basicConfig(level= logging.WRAN)
# logging.basicConfig(level=logging.WARNING)
# logging.basicConfig(level=logging.ERROR)
logging.basicConfig(level=logging.CRITICAL)
logging.debug('this is debug info')
logging.info('info is : hello you')
logging.warning('warning info')
logging.error('this is error info')
logging.critical('critical info')
- the output of level=logging.DEBUG *
DEBUG:root:this is debug info
INFO:root:info is : hello you
WARNING:root:warning info
ERROR:root:this is error info
CRITICAL:root:critical info
- the output of level=logging.CRITICAL *
ERROR:root:this is error info
CRITICAL:root:critical info
1.2 日誌的格式
格式 描述
%(levelno)s 打印日誌級別的數值
%(levelname)s 打印日誌級別名稱
%(pathname)s 打印當前執行程序的路徑
%(filename)s 打印當前執行程序名稱
%(funcName)s 打印日誌的當前函數
%(lineno)d 打印日誌的當前行號
%(asctime)s 打印日誌的時間
%(thread)d 打印線程id
%(threadName)s 打印線程名稱
%(process)d 打印進程ID
%(message)s 打印日誌信息
在logging庫中定義如下：
CRITICAL = 50
FATAL = CRITICAL
ERROR = 40
WARNING = 30
WARN = WARNING
INFO = 20
DEBUG = 10
NOTSET = 0
logging.basicConfig(level=logging.DEBUG,filename='../log/runlog.log',format='%(levelno)s %(asctime)s %(threadName)s %(filename)s %(lineno)d %(levelname)s %(message)s')
the output
10 2018-12-05 16:38:00,982 MainThread log_practice.py 25 DEBUG this is debug info
20 2018-12-05 16:38:00,982 MainThread log_practice.py 26 INFO info is : hello you
30 2018-12-05 16:38:00,982 MainThread log_practice.py 27 WARNING warning info
40 2018-12-05 16:38:00,982 MainThread log_practice.py 28 ERROR this is error info
50 2018-12-05 16:38:00,982 MainThread log_practice.py 29 CRITICAL critical info
1.3 日誌參數配置分離
配置文件的理解！！！！, 學習一下
