我已经知道了颜色转义，我使用他们在我的bash提示前一段时间。不管怎样,都要谢谢您。 我想要的是将它与日志模块集成在一起，经过几次尝试和错误后，我最终做到了这一点。 这是我最后得出的结论:

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

#The background is set with 40 plus the number of the color, and the foreground with 30

#These are the sequences need to get colored ouput
RESET_SEQ = "\033[0m"
COLOR_SEQ = "\033[1;%dm"
BOLD_SEQ = "\033[1m"

def formatter_message(message, use_color = True):
    if use_color:
        message = message.replace("$RESET", RESET_SEQ).replace("$BOLD", BOLD_SEQ)
    else:
        message = message.replace("$RESET", "").replace("$BOLD", "")
    return message

COLORS = {
    'WARNING': YELLOW,
    '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
        if self.use_color and levelname in COLORS:
            levelname_color = COLOR_SEQ % (30 + COLORS[levelname]) + levelname + RESET_SEQ
            record.levelname = levelname_color
        return logging.Formatter.format(self, record)

要使用它，请创建自己的Logger:

# Custom logger class with multiple destinations
class ColoredLogger(logging.Logger):
    FORMAT = "[$BOLD%(name)-20s$RESET][%(levelname)-18s]  %(message)s ($BOLD%(filename)s$RESET:%(lineno)d)"
    COLOR_FORMAT = formatter_message(FORMAT, True)
    def __init__(self, name):
        logging.Logger.__init__(self, name, logging.DEBUG)                

        color_formatter = ColoredFormatter(self.COLOR_FORMAT)

        console = logging.StreamHandler()
        console.setFormatter(color_formatter)

        self.addHandler(console)
        return


logging.setLoggerClass(ColoredLogger)

以防有人需要。

Be careful if you're using more than one logger or handler: ColoredFormatter is changing the record object, which is passed further to other handlers or propagated to other loggers. If you have configured file loggers etc. you probably don't want to have the colors in the log files. To avoid that, it's probably best to simply create a copy of record with copy.copy() before manipulating the levelname attribute, or to reset the levelname to the previous value, before returning the formatted string (credit to Michael in the comments).

使用pyfancy。

例子:

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

快速和肮脏的解决方案预定义的日志级别，而不定义一个新的类。

logging.addLevelName( logging.WARNING, "\033[1;31m%s\033[1;0m" % logging.getLevelName(logging.WARNING))
logging.addLevelName( logging.ERROR, "\033[1;41m%s\033[1;0m" % logging.getLevelName(logging.ERROR))

FriendlyLog是另一种选择。它适用于Linux、Windows和MacOS下的Python 2和3。

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())

最简单的解决办法可能是科罗拉多州。

在你的电脑上安装Colorama:

pip install colorama

然后把它添加到你的Python程序中:

import colorama
print(Fore.GREEN + "test123")

如果你需要多颜色的东西，使用YAChalk。

在你的电脑上安装YAChalk:

pip install yachalk

将它添加到你的Python程序中:

from yachalk import chalk
print(chalk.blue("This is blue and {chalk.red("this is red")})
