python日志的使用
1、日志设置
1 import logging 2 3 global logger # 设置全局变量,涉及动态修改 4 g_logDir = "D:/checkerPath/logs/" 5 6 def tearUp(): 7 # 创建一个logger 8 global root_logger 9 global fh 10 global ch 11 12 root_logger = logging.getLogger("clkLogger") 13 root_logger.setLevel(logging.DEBUG) 14 15 # 创建一个handler,用于写入日志文件 16 fh = logging.FileHandler(logDir) 17 fh.setLevel(logging.DEBUG) 18 19 # 再创建一个handler,用于输出到控制台 20 ch = logging.StreamHandler() 21 ch.setLevel(logging.DEBUG) 22 23 # 定义handler的输出格式 24 formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(pathname)s - %(lineno)s - %(message)s') 25 fh.setFormatter(formatter) 26 ch.setFormatter(formatter) 27 28 # 给logger添加handler 29 root_logger.addHandler(fh) 30 root_logger.addHandler(ch) 31 logger = root_logger; # 修改全局日志变量 32 33 logger.info(explain(configItem[1])) 34 35 36 def tear_down(): 37 logger.debug("close the log handler") 38 root_logger.removeHandler(fh) 39 root_logger.removeHandler(ch) 40 logger.removeHandler(fh) 41 logger.removeHandler(ch)
使用方法
import logging
logger = logging.getLogger("clkLogger.libClk")
logger.debug("获取的参数信息为:"+ str(g_clock_sourceA["5"]))
