python日志输出—logging直接代码配置

一、logging直接写在代码中

def log_test01():
    import logging
    import logging.handlers
    LOG_FILE = "../log/test01.log"
    handler = logging.handlers.RotatingFileHandler(LOG_FILE, maxBytes = 20*1024*1024, backupCount = 10); # 实例化handler
    fmt = "%(asctime)s - %(name)s - %(levelname)s - %(message)s - [%(filename)s:%(lineno)s]"
    formatter = logging.Formatter(fmt);   # 实例化formatter  
    handler.setFormatter(formatter);      # 为handler添加formatter  

    logger = logging.getLogger('xzs');    # 获取名为xzs的logger  
    logger.addHandler(handler);           # 为logger添加handler  
    logger.setLevel(logging.DEBUG)
    
    logger.debug("Hello boy, Debug");
    logger.info("Hello boy, Info");

if __name__ == "__main__":
    log_test01()
    

输出结果

2012-06-04 14:48:13,606 - xzs - DEBUG - Hello boy, Debug - [xlog.py:20]
2012-06-04 14:48:13,606 - xzs - INFO - Hello boy, Info - [xlog.py:21]

这种直接配置比较简单，但不够灵活
