另一个解决方案，用ZetaSyanthis的颜色:

def config_log(log_level):

    def set_color(level, code):
        level_fmt = "\033[1;" + str(code) + "m%s\033[1;0m" 
        logging.addLevelName( level, level_fmt % logging.getLevelName(level) )

    std_stream = sys.stdout
    isatty = getattr(std_stream, 'isatty', None)
    if isatty and isatty():
        levels = [logging.DEBUG, logging.CRITICAL, logging.WARNING, logging.ERROR]
        for idx, level in enumerate(levels):
            set_color(level, 30 + idx )
        set_color(logging.DEBUG, 0)
    logging.basicConfig(stream=std_stream, level=log_level)

在__main__函数中调用它一次。我这里有这样的东西:

options, arguments = p.parse_args()
log_level = logging.DEBUG if options.verbose else logging.WARNING
config_log(log_level)

它还验证输出是否为控制台，否则不使用颜色。

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).

我遇到的麻烦是正确设置格式化程序:

class ColouredFormatter(logging.Formatter):    
    def __init__(self, msg):
        logging.Formatter.__init__(self, msg)
        self._init_colour = _get_colour()

    def close(self):
        # restore the colour information to what it was
        _set_colour(self._init_colour)

    def format(self, record):        
        # Add your own colourer based on the other examples
        _set_colour( LOG_LEVEL_COLOUR[record.levelno] )
        return logging.Formatter.format(self, record)         

def init():
    # Set up the formatter. Needs to be first thing done.
    rootLogger = logging.getLogger()
    hdlr = logging.StreamHandler()
    fmt = ColouredFormatter('%(message)s')
    hdlr.setFormatter(fmt)
    rootLogger.addHandler(hdlr)

然后使用:

import coloured_log
import logging

coloured_log.init()
logging.info("info")    
logging.debug("debug")    

coloured_log.close()    # restore colours

以下是我的解决方案:

class ColouredFormatter(logging.Formatter):
    RESET = '\x1B[0m'
    RED = '\x1B[31m'
    YELLOW = '\x1B[33m'
    BRGREEN = '\x1B[01;32m'  # grey in solarized for terminals

    def format(self, record, colour=False):
        message = super().format(record)

        if not colour:
            return message

        level_no = record.levelno
        if level_no >= logging.CRITICAL:
            colour = self.RED
        elif level_no >= logging.ERROR:
            colour = self.RED
        elif level_no >= logging.WARNING:
            colour = self.YELLOW
        elif level_no >= logging.INFO:
            colour = self.RESET
        elif level_no >= logging.DEBUG:
            colour = self.BRGREEN
        else:
            colour = self.RESET

        message = colour + message + self.RESET

        return message


class ColouredHandler(logging.StreamHandler):
    def __init__(self, stream=sys.stdout):
        super().__init__(stream)

    def format(self, record, colour=False):
        if not isinstance(self.formatter, ColouredFormatter):
            self.formatter = ColouredFormatter()

        return self.formatter.format(record, colour)

    def emit(self, record):
        stream = self.stream
        try:
            msg = self.format(record, stream.isatty())
            stream.write(msg)
            stream.write(self.terminator)
            self.flush()
        except Exception:
            self.handleError(record)


h = ColouredHandler()
h.formatter = ColouredFormatter('{asctime} {levelname:8} {message}', '%Y-%m-%d %H:%M:%S', '{')
logging.basicConfig(level=logging.DEBUG, handlers=[h])

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")})

airmind的另一种方法是将所有东西都放在一个类中:

class ColorFormatter(logging.Formatter):
  FORMAT = ("[$BOLD%(name)-20s$RESET][%(levelname)-18s]  "
            "%(message)s "
            "($BOLD%(filename)s$RESET:%(lineno)d)")

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

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

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

  def formatter_msg(self, msg, use_color = True):
    if use_color:
      msg = msg.replace("$RESET", self.RESET_SEQ).replace("$BOLD", self.BOLD_SEQ)
    else:
      msg = msg.replace("$RESET", "").replace("$BOLD", "")
    return msg

  def __init__(self, use_color=True):
    msg = self.formatter_msg(self.FORMAT, use_color)
    logging.Formatter.__init__(self, msg)
    self.use_color = use_color

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

要使用将格式化程序附加到处理程序，如下所示:

handler.setFormatter(ColorFormatter())
logger.addHandler(handler)
