我已经使用了一个基本的日志配置,其中所有模块的所有消息都存储在一个文件中。然而,我现在需要一个更复杂的解决方案:

  • 两个文件:第一个保持不变。
  • 第二个文件应该有一些自定义格式。

我一直在阅读模块的文档,但目前它们对我来说非常复杂。记录器,处理程序...
因此,简而言之:
如何在Python 3中记录两个文件,即:

import logging
# ...
logging.file1.info('Write this to file 1')
logging.file2.info('Write this to file 2')

你可以这样做:

import logging
formatter = logging.Formatter('%(asctime)s %(levelname)s %(message)s')

def setup_logger(name, log_file, level=logging.INFO):
    """To setup as many loggers as you want"""

    handler = logging.FileHandler(log_file)        
    handler.setFormatter(formatter)

    logger = logging.getLogger(name)
    logger.setLevel(level)
    logger.addHandler(handler)

    return logger

# first file logger
logger = setup_logger('first_logger', 'first_logfile.log')
logger.info('This is just info message')

# second file logger
super_logger = setup_logger('second_logger', 'second_logfile.log')
super_logger.error('This is an error message')

def another_method():
   # using logger defined above also works here
   logger.info('Inside method')

def setup_logger(logger_name, log_file, level=logging.INFO):
    l = logging.getLogger(logger_name)
    formatter = logging.Formatter('%(message)s')
    fileHandler = logging.FileHandler(log_file, mode='w')
    fileHandler.setFormatter(formatter)
    streamHandler = logging.StreamHandler()
    streamHandler.setFormatter(formatter)

    l.setLevel(level)
    l.addHandler(fileHandler)
    l.addHandler(streamHandler)    

setup_logger('log1', txtName+"txt")
setup_logger('log2', txtName+"small.txt")
logger_1 = logging.getLogger('log1')
logger_2 = logging.getLogger('log2')



logger_1.info('111messasage 1')
logger_2.info('222ersaror foo')
