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")
