python日志通过不同的等级打印不同的颜色

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")
