python使用logging配置日志，方式如下：

1、添加日志配置文件

[loggers]
    keys=root,simpleExample,app,generateImg
    
    [handlers]
    keys=fileHandler,consoleHandler
    
    [formatters]
    keys=simpleFormatter,app,generateImg
    
    [logger_root]
    level=DEBUG
    handlers=fileHandler
    
    [logger_simpleExample]
    level=DEBUG
    handlers=consoleHandler
    qualname=simpleExample
    propagate=0
    
    [logger_app]
    level=DEBUG
    handlers=consoleHandler
    qualname=app
    propagate=0
    
    [logger_generateImg]
    level=DEBUG
    handlers=consoleHandler
    qualname=generateImg
    propagate=0
    
    [handler_consoleHandler]
    class=StreamHandler
    args=(sys.stdout,)
    level=DEBUG
    formatter=simpleFormatter
    
    [handler_fileHandler]
    class=FileHandler
    args=('logging.log', 'a')
    level=ERROR
    formatter=simpleFormatter
    
    [formatter_simpleFormatter]
    format=%(asctime)s - %(name)s - %(levelname)s - %(message)s
    datefmt=
    
    [formatter_app]
    format=%(asctime)s - %(name)s - %(levelname)s - %(message)s
    datefmt=
    
    [formatter_generateImg]
    format=%(asctime)s - %(name)s - %(levelname)s - %(message)s
    datefmt=

2、在程序中引用并且配置日志内容

#!/usr/bin/python
    # -*- coding:utf8 -*-
    import logging.config
    
    WORK_SPACE = '/Users/wuxueyou/Project/python/imageGenerator'
    
    # 读取日志配置文件内容
    logging.config.fileConfig('%s/resources/logging.conf' % WORK_SPACE)
    
    # 创建一个日志器logger
    logger = logging.getLogger('app')
    
    if __name__ == '__main__':
        logger.debug("debug")
        logger.info("info")
        logger.warn("warn")
        logger.error("error")

3、程序运行结果：

2018-09-09 22:20:15,574 - app - DEBUG - debug  
2018-09-09 22:20:15,574 - app - INFO - info  
2018-09-09 22:20:15,574 - app - WARNING - warn  
2018-09-09 22:20:15,574 - app - ERROR - error
