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 

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])

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]
)

安装colorlog包，你可以立即在你的日志消息中使用颜色:

获取一个记录器实例，就像您通常所做的那样。 设置日志级别。您也可以使用像DEBUG这样的常量 和INFO从日志模块直接。 将消息格式化程序设置为所提供的ColoredFormatter 通过colorlog库。

import colorlog

logger = colorlog.getLogger()
logger.setLevel(colorlog.colorlog.logging.DEBUG)

handler = colorlog.StreamHandler()
handler.setFormatter(colorlog.ColoredFormatter())
logger.addHandler(handler)

logger.debug("Debug message")
logger.info("Information message")
logger.warning("Warning message")
logger.error("Error message")
logger.critical("Critical message")

输出:

更新:额外信息

只需更新ColoredFormatter:

handler.setFormatter(colorlog.ColoredFormatter('%(log_color)s [%(asctime)s] %(levelname)s [%(filename)s.%(funcName)s:%(lineno)d] %(message)s', datefmt='%a, %d %b %Y %H:%M:%S'))

输出:

包:

pip install colorlog

输出:

我更喜欢使用这个片段:

import logging
from enum import Enum

CSI = '\033['

Color = Enum(
    'Color', 'BLACK RED GREEN YELLOW BLUE MAGENTA CYAN WHITE', start=30
)


class AnsiColorHandler(logging.StreamHandler):
    LOGLEVEL_COLORS = {
        'DEBUG': Color.BLUE,
        'INFO': Color.GREEN,
        'WARNING': Color.RED,
        'ERROR': Color.RED,
        'CRITICAL': Color.RED,
    }

    def __init__(self) -> None:
        super().__init__()
        self.formatter = logging.Formatter("%(levelname)-8s - %(message)s")

    def format(self, record: logging.LogRecord) -> str:
        message: str = super().format(record)
        # use colors in tty
        if self.stream.isatty() and (
            color := self.LOGLEVEL_COLORS.get(record.levelname)
        ):
            message = f'{CSI}{color.value}m{message}{CSI}0m'
        return message


# setup logger
# logger = logging.getLogger(__package__)
logger = logging.getLogger(__name__)
logger.addHandler(AnsiColorHandler())

用法:

import logging

from .log import logger

logger.setLevel(logging.DEBUG)
logger.debug("aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa")

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