如果有人正在寻找一个漂亮的着色以及自定义日志级别着色，你可以看看这个改编的解决方案(它使用moecololelibrary):

#Install moecolor
pip install moecolor

from moecolor import FormatText as ft

class ConsoleFormatter(logging.Formatter):
    default_format = f"[%(asctime)s | %(name)s | %(funcName)s | LN%(lineno)s | %(levelname)s]: %(message)s"
    time_portion =  ft('%(asctime)s', color='purple').text
    format_portion = ' | %(name)s | %(funcName)s | LN%(lineno)d | %(levelname)s]: '
    FORMATS = {
        'DEBUG': time_portion + ft(format_portion, color='yellow').text + ft('%(message)s', color='fff9ae').text,
        'INFO': time_portion + ft(format_portion, color='green').text + ft('%(message)s', color='#d3ffb3').text,
        'WARNING': time_portion + ft(format_portion, color='orange').text + ft('%(message)s', color='#ffc100').text,
        'TIMER': time_portion + ft(format_portion, color='blue').text + ft('%(message)s', color='#00b4d8').text, # Note, this is a custom log level
        'ERROR': time_portion + ft(format_portion, color='red').text + ft('%(message)s', color='#ba262b').text,
        'CRITICAL': time_portion + ft(format_portion, color='#8D0101').text + ft('%(message)s', color='#D5212E').text,
    }

    def format(self, record):
        _format = self.FORMATS.get(record.levelname, self.default_format)
        formatter = logging.Formatter(_format)
        return formatter.format(record)

你可以这样使用它:

console_handler = logging.StreamHandler()
console_handler.setFormatter(ConsoleFormatter())

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]
)

import logging

logging.basicConfig(filename="f.log" filemode='w', level=logging.INFO,
                    format = "%(logger_name)s %(color)s  %(message)s %(endColor)s")


class Logger(object):
    __GREEN = "\033[92m"
    __RED = '\033[91m'
    __ENDC = '\033[0m'

    def __init__(self, name):
        self.logger = logging.getLogger(name)
        self.extra={'logger_name': name, 'endColor': self.__ENDC, 'color': self.__GREEN}


    def info(self, msg):
        self.extra['color'] = self.__GREEN
        self.logger.info(msg, extra=self.extra)

    def error(self, msg):
        self.extra['color'] = self.__RED
        self.logger.error(msg, extra=self.extra)

使用

日志记录器("文件名").info("显示绿色文本")

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 

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()])

使用pyfancy。

例子:

print(pyfancy.RED + "Hello Red!" + pyfancy.END)
