python日志通过不同的等级打印不同的颜色(示例代码)

1，不用第三方库

# coding: utf-8
import logging

black, red, green, yellow, blue, magenta, cyan, white = range(8)
reset_seq = "\033[0m"
color_seq = "\033[1;%dm"

colors = {
 'warning': green,
 'info': white,
 'debug': blue,
 'critical': yellow,
 'error': red
}

class coloredformatter(logging.formatter):
 def __init__(self, msg, use_color=true):
  logging.formatter.__init__(self, msg)
  self.use_color = use_color

 def format(self, record):
  levelname = record.levelname
  message = str(record.msg)
  funcname = record.funcname
  if self.use_color and levelname in colors:
   levelname_color = color_seq % (30 + colors[levelname]) + levelname + reset_seq
   message_color = color_seq % (30 + colors[levelname]) + message + reset_seq
   funcname_color = color_seq % (30 + colors[levelname]) + funcname + reset_seq
   record.levelname = levelname_color
   record.msg = message_color
   record.funcname = funcname_color
  return logging.formatter.format(self, record)

logformat = "[%(asctime)s][%(name)s] [%(levelname)s] (%(filename)s:%(funcname)s:%(lineno)d) %(message)s"
log_level = logging.debug
formatter = coloredformatter(logformat)
stream = logging.streamhandler()
stream.setlevel(log_level)
stream.setformatter(formatter)
logging.root.setlevel(log_level)
log = logging.getlogger('logconfig')
log.setlevel(log_level)
log.addhandler(stream)
def logging(name):
 log = logging.getlogger(name)
 log.setlevel(log_level)
 log.addhandler(stream)
 return log

if __name__ == '__main__':
 logger = logging(__name__)
 logger.info(123123)
 logger.debug(123123)
 logger.error(123123)
 logger.warning(123123)

 

2，使用colorlog pip install colorlog

# coding: utf-8
# coding: utf-8
from colorlog import coloredformatter
import logging

log_level = logging.debug

logformat = "[%(asctime)s][%(name)s] [%(log_color)s**%(levelname)s**%(reset)s] [%(filename)s:%(funcname)s:%(log_color)s%(lineno)d%(reset)s] %(log_color)s%(message)s%(reset)s"
logging.root.setlevel(log_level)
formatter = coloredformatter(logformat)

stream = logging.streamhandler()
stream.setlevel(log_level)
stream.setformatter(formatter)

log = logging.getlogger('logconfig')
log.setlevel(log_level)
log.addhandler(stream)

def logging(name):
 log = logging.getlogger(name)
 log.setlevel(log_level)
 log.addhandler(stream)
 return log

if __name__ == '__main__':
 logging = logging("test")
 logging.info(123123)
 logging.warning(123123)
 logging.debug(123123)

3，华丽的日志

pip install logbook termcc dataclasses

#coding: utf-8
from logbook import logger
from termcc.helper.logger import sample_flask as setup_logger
setup_logger()

logging = logger(__name__)
logging.info("123123")
logging.debug("123123")
logging.warn("123123")
