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")

这是airmind示例的另一个Python3变体。我想要一些在其他例子中没有看到的特性

为终端使用颜色，但不要在文件处理程序中写入不可打印的字符(我为此定义了2个格式化器) 能够覆盖特定日志消息的颜色 从一个文件(在本例中是yaml)配置记录器

注意:我使用了colorama，但是你可以修改它，这样就不需要了。对于我的测试，我只是运行python文件，所以我的类在模块__main__中。你必须更改():__main__。ColoredFormatter到你的模块。

pip install colorama pyyaml

logging.yaml

Instalation

pip install coloredlogs

使用

最小的用法:

import logging
import coloredlogs

coloredlogs.install()  # install a handler on the root logger

logging.debug('message with level debug')
logging.info('message with level info')
logging.warning('message with level warning')
logging.error('message with level error')
logging.critical('message with level critical')

结果:

从消息级调试开始:

import logging
import coloredlogs

coloredlogs.install(level='DEBUG')  # install a handler on the root logger with level debug

logging.debug('message with level debug')
logging.info('message with level info')
logging.warning('message with level warning')
logging.error('message with level error')
logging.critical('message with level critical')

结果:

从库中隐藏消息:

import logging
import coloredlogs

logger = logging.getLogger(__name__)  # get a specific logger object
coloredlogs.install(level='DEBUG')  # install a handler on the root logger with level debug
coloredlogs.install(level='DEBUG', logger=logger)  # pass a specific logger object

logging.debug('message with level debug')
logging.info('message with level info')
logging.warning('message with level warning')
logging.error('message with level error')
logging.critical('message with level critical')

结果:

格式化日志消息:

import logging
import coloredlogs

logger = logging.getLogger(__name__)  # get a specific logger object
coloredlogs.install(level='DEBUG')  # install a handler on the root logger with level debug
coloredlogs.install(level='DEBUG', logger=logger)  # pass a specific logger object
coloredlogs.install(
    level='DEBUG', logger=logger,
    fmt='%(asctime)s.%(msecs)03d %(filename)s:%(lineno)d %(levelname)s %(message)s'
)

logging.debug('message with level debug')
logging.info('message with level info')
logging.warning('message with level warning')
logging.error('message with level error')
logging.critical('message with level critical')

结果:

可用的格式属性:

%(asctime)s - Time as human-readable string, when logging call was issued %(created)f - Time as float when logging call was issued %(filename)s - File name %(funcName)s - Name of function containing the logging call %(hostname)s - System hostname %(levelname)s - Text logging level %(levelno)s - Integer logging level %(lineno)d - Line number where the logging call was issued %(message)s - Message passed to logging call (same as %(msg)s) %(module)s - File name without extension where the logging call was issued %(msecs)d - Millisecond part of the time when logging call was issued %(msg)s - Message passed to logging call (same as %(message)s) %(name)s - Logger name %(pathname)s - Full pathname to file containing the logging call %(process)d - Process ID %(processName)s - Process name %(programname)s - System programname %(relativeCreated)d - Time as integer in milliseconds when logging call was issued, relative to the time when logging module was loaded %(thread)d - Thread ID %(threadName)s - Thread name %(username)s - System username

日志库

import logging
import sys

colors = {'pink': '\033[95m', 'blue': '\033[94m', 'green': '\033[92m', 'yellow': '\033[93m', 'red': '\033[91m',
      'ENDC': '\033[0m', 'bold': '\033[1m', 'underline': '\033[4m'}

logging.basicConfig(stream=sys.stdout, level=logging.DEBUG)


def str_color(color, data):
    return colors[color] + str(data) + colors['ENDC']

params = {'param1': id1, 'param2': id2}

logging.info('\nParams:' + str_color("blue", str(params)))`

刚刚回答了类似的问题:Python |在shell中更改文本颜色

这个想法是使用clint库。它支持MAC, Linux和Windows shell (CLI)。

使用pyfancy。

例子:

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