基本范式是:

try:

    do-something-block

except:

    logger.exception("Exception Logged")

def setLogger():  
    # 创建一个logger,可以考虑如何将它封装  
    logger = logging.getLogger('mylogger')  
    logger.setLevel(logging.DEBUG)  

    # 创建一个handler,用于写入日志文件  
    fh = logging.FileHandler(os.path.join(os.getcwd(), 'log.txt'))  
    fh.setLevel(logging.DEBUG)  

    # 再创建一个handler,用于输出到控制台  
    ch = logging.StreamHandler()  
    ch.setLevel(logging.DEBUG)  

    # 定义handler的输出格式  
    formatter = logging.Formatter('%(asctime)s - %(module)s.%(funcName)s.%(lineno)d - %(levelname)s - %(message)s')  
    fh.setFormatter(formatter)  
    ch.setFormatter(formatter)  

    # 给logger添加handler  
    logger.addHandler(fh)  
    logger.addHandler(ch)  

    # 记录一条日志  
    logger.info('hello world, i'm log helper in python, may i help you')  
    return logger  



#对单个表插入一个元组,其定义有
