The following is a sample code for python to implement log log. It has a good reference value and I hope it will be helpful to everyone. Let’s take a look together

# coding=utf-8
import logging
import os
import time
LEVELS={&#39;debug&#39;:logging.DEBUG,\
  &#39;info&#39;:logging.INFO,\
  &#39;warning&#39;:logging.WARNING,\
  &#39;error&#39;:logging.ERROR,\
  &#39;critical&#39;:logging.CRITICAL,}
logger=logging.getLogger()
level=&#39;default&#39;
def createFile(filename):
 path=filename[0:filename.rfind(&#39;/&#39;)]
 if not os.path.isdir(path):
  os.makedirs(path)
 if not os.path.isfile(filename):
#创建并打开一个新文件
  fd = open(filename,mode=&#39;w&#39;,encoding=&#39;utf-8&#39;)
  fd.close()
class MyLog:
 log_filename=&#39;E:/quality/it/pyrequest-master/log/itest.log&#39;
 err_filename=&#39;E:/quality/it/pyrequest-master/log/err.log&#39;
 dateformat=&#39;%Y-%m-%d %H:%M:%S&#39;
 logger.setLevel(LEVELS.get(level,logging.NOTSET))
 createFile(log_filename)
 createFile(err_filename)
#注意文件内容写入时编码格式指定
 handler=logging.FileHandler(log_filename,encoding=&#39;utf-8&#39;)
 errhandler=logging.FileHandler(err_filename,encoding=&#39;utf-8&#39;)
 @staticmethod 
 #静态方法
 def debug(log_message):
  setHandler(&#39;debug&#39;)
  logger.debug("[DEBUG "+getCurrentTime()+"]"+log_message)
  removerhandler(&#39;debug&#39;)
 @staticmethod
 def info(log_message):
  setHandler(&#39;info&#39;)
  logger.info("[INFO "+getCurrentTime()+"]"+log_message)
  removerhandler(&#39;info&#39;)
 @staticmethod
 def warning(log_message):
  setHandler(&#39;warning&#39;)
  logger.warning("[WARNING "+getCurrentTime()+"]"+log_message)
  removerhandler(&#39;warning&#39;)
 @staticmethod
 def error(log_message):
  setHandler(&#39;error&#39;)
  logger.error("[ERROR "+getCurrentTime()+"]"+log_message)
  removerhandler(&#39;error&#39;)
 @staticmethod
 def critical(log_message):
  setHandler(&#39;critical&#39;)
  logger.critical("[CRITICAL "+getCurrentTime()+"]"+log_message)
  removerhandler(&#39;critical&#39;)
# logger可以看做是一个记录日志的人，对于记录的每个日志，他需要有一套规则，比如记录的格式（formatter），
# 等级（level）等等，这个规则就是handler。使用logger.addHandler(handler)添加多个规则，
# 就可以让一个logger记录多个日志。
def setHandler(level):
 if level==&#39;error&#39;:
  logger.addHandler(MyLog.errhandler)
 #handler=logging.FileHandler(log_filename)
 #把logger添加上handler
 logger.addHandler(MyLog.handler)
def removerhandler(level):
 if level==&#39;error&#39;:
  logger.removeHandler(MyLog.errhandler)
 logger.removeHandler(MyLog.handler)
def getCurrentTime():
 return time.strftime(MyLog.dateformat,time.localtime(time.time()))
if __name__=="__main__":
 MyLog.debug("This is debug message")
 MyLog.info("This is info message")
 MyLog.warning("This is warning message")
 MyLog.error("This is error message")
 MyLog.critical("This is critical message")
