这是@Sergey Pleshakov的出色回答的轻微变化，他只对关卡使用颜色，并像预期的那样使用basicConfig:

class CustomFormatter(logging.Formatter):

    white = "\x1b[97;20m"
    grey = "\x1b[38;20m"
    green = "\x1b[32;20m"
    cyan = "\x1b[36;20m"
    yellow = "\x1b[33;20m"
    red = "\x1b[31;20m"
    bold_red = "\x1b[31;1m"
    reset = "\x1b[0m"
    fmt = "%(asctime)s - {}%(levelname)-8s{} - %(name)s.%(funcName)s - %(message)s"

    FORMATS = {
        logging.DEBUG: fmt.format(grey, reset),
        logging.INFO: fmt.format(green, reset),
        logging.WARNING: fmt.format(yellow, reset),
        logging.ERROR: fmt.format(red, reset),
        logging.CRITICAL: fmt.format(bold_red, reset),
    }

    def format(self, record):
        log_fmt = self.FORMATS.get(record.levelno)
        formatter = logging.Formatter(log_fmt, datefmt="%H:%M:%S")
        return formatter.format(record)


handler = logging.StreamHandler()
handler.setFormatter(CustomFormatter())
logging.basicConfig(
    level=logging.DEBUG,
    handlers=[handler]
)

我从airmind中更新了支持前景和背景标签的示例。 只需在日志格式化器字符串中使用颜色变量$BLACK - $WHITE即可。设置背景只需使用$BG-BLACK - $BG-WHITE。

import logging

BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE = range(8)

COLORS = {
    'WARNING'  : YELLOW,
    'INFO'     : WHITE,
    'DEBUG'    : BLUE,
    'CRITICAL' : YELLOW,
    'ERROR'    : RED,
    'RED'      : RED,
    'GREEN'    : GREEN,
    'YELLOW'   : YELLOW,
    'BLUE'     : BLUE,
    'MAGENTA'  : MAGENTA,
    'CYAN'     : CYAN,
    'WHITE'    : WHITE,
}

RESET_SEQ = "\033[0m"
COLOR_SEQ = "\033[1;%dm"
BOLD_SEQ  = "\033[1m"

class ColorFormatter(logging.Formatter):

    def __init__(self, *args, **kwargs):
        # can't do super(...) here because Formatter is an old school class
        logging.Formatter.__init__(self, *args, **kwargs)

    def format(self, record):
        levelname = record.levelname
        color     = COLOR_SEQ % (30 + COLORS[levelname])
        message   = logging.Formatter.format(self, record)
        message   = message.replace("$RESET", RESET_SEQ)\
                           .replace("$BOLD",  BOLD_SEQ)\
                           .replace("$COLOR", color)
        for k,v in COLORS.items():
            message = message.replace("$" + k,    COLOR_SEQ % (v+30))\
                             .replace("$BG" + k,  COLOR_SEQ % (v+40))\
                             .replace("$BG-" + k, COLOR_SEQ % (v+40))
        return message + RESET_SEQ

logging.ColorFormatter = ColorFormatter

所以现在你可以在配置文件中简单地执行以下操作:

[formatter_colorFormatter]
class=logging.ColorFormatter
format= $COLOR%(levelname)s $RESET %(asctime)s $BOLD$COLOR%(name)s$RESET %(message)s

一个方便的带有tput颜色的bash脚本

# Simple using tput
bold=$(tput bold)
reset=$(tput sgr0)

fblack=$(tput setaf 0)
fred=$(tput setaf 1)
fgreen=$(tput setaf 2)
fyellow=$(tput setaf 3)
fblue=$(tput setaf 4)
fmagenta=$(tput setaf 5)
fcyan=$(tput setaf 6)
fwhite=$(tput setaf 7)
fnotused=$(tput setaf 8)
freset=$(tput setaf 9)

bblack=$(tput setab 0)
bred=$(tput setab 1)
bgreen=$(tput setab 2)
byellow=$(tput setab 3)
bblue=$(tput setab 4)
bmagenta=$(tput setab 5)
bcyan=$(tput setab 6)
bwhite=$(tput setab 7)
bnotused=$(tput setab 8)
breset=$(tput setab 9)

# 0 - Emergency (emerg)       $fred       # something is wrong... go red
# 1 - Alerts (alert)          $fred       # something is wrong... go red
# 2 - Critical (crit)         $fred       # something is wrong... go red
# 3 - Errors (err)            $fred       # something is wrong... go red
# 4 - Warnings (warn)         $fyellow    # yellow yellow dirty logs
# 5 - Notification (notice)   $fwhite     # common stuff
# 6 - Information (info)      $fblue      # sky is blue
# 7 - Debug (debug)           $fgreen     # lot of stuff to read... go green 

只要你不想去发明轮子。

只需pip安装loguru，然后:

from loguru import logger

if __name__ == '__main__':
    message = "Message text"

    logger.info(message)
    logger.debug(message)
    logger.warning(message)
    logger.success(message)
    logger.error(message)
    logger.critical(message)

输出:

您可以更改格式，颜色，写入文件从盒子…这里是文档

简化的日志库:

class handler(logging.StreamHandler):
    colors = {
        logging.DEBUG: '\033[37m',
        logging.INFO: '\033[36m',
        logging.WARNING: '\033[33m',
        logging.ERROR: '\033[31m',
        logging.CRITICAL: '\033[101m',
    }
    reset = '\033[0m'
    fmtr = logging.Formatter('%(levelname)s %(message)s')

    def format(self, record):
        color = self.colors[record.levelno]
        log = self.fmtr.format(record)
        reset = self.reset
        return color + log + reset


logging.basicConfig(level=logging.DEBUG, handlers=[handler()])

我修改了Sorin提供的原始示例，并将StreamHandler子类化为ColorizedConsoleHandler。

他们的解决方案的缺点是它修改了消息，并且因为修改了实际的日志消息，任何其他处理程序也将得到修改后的消息。

在我们的例子中，这导致日志文件中有颜色代码，因为我们使用了多个记录器。

下面的类只在支持ANSI的平台上工作，但是向它添加Windows颜色代码应该很简单。

import copy
import logging


class ColoredConsoleHandler(logging.StreamHandler):
    def emit(self, record):
        # Need to make a actual copy of the record
        # to prevent altering the message for other loggers
        myrecord = copy.copy(record)
        levelno = myrecord.levelno
        if(levelno >= 50):  # CRITICAL / FATAL
            color = '\x1b[31m'  # red
        elif(levelno >= 40):  # ERROR
            color = '\x1b[31m'  # red
        elif(levelno >= 30):  # WARNING
            color = '\x1b[33m'  # yellow
        elif(levelno >= 20):  # INFO
            color = '\x1b[32m'  # green
        elif(levelno >= 10):  # DEBUG
            color = '\x1b[35m'  # pink
        else:  # NOTSET and anything else
            color = '\x1b[0m'  # normal
        myrecord.msg = color + str(myrecord.msg) + '\x1b[0m'  # normal
        logging.StreamHandler.emit(self, myrecord)
