日志层次结构与根日志?

巨蟒 logging

使用 getLogger() 功能。函数调用 logging.getLogger('debug0.x') x 是一个孩子 debug0 它本身是根记录器的子级。当记录到此记录器时,它将把消息传递给其父记录器,其父记录器将把消息传递给根记录器。您将根日志记录器配置为通过 basicConfig() 函数,所以您的消息将在那里结束。

如果您签出代码或文档:

>>> print logging.basicConfig.__doc__

    Do basic configuration for the logging system.

    This function does nothing if the root logger already has handlers
    configured. ...............
    A number of optional keyword arguments may be specified, which can alter
    the default behaviour.

    filename  Specifies that a FileHandler be created, using the specified
              filename, rather than a StreamHandler.
    filemode  Specifies the mode to open the file, if filename is specified
              (if filemode is unspecified, it defaults to 'a').
    format    Use the specified format string for the handler.
    datefmt   Use the specified date/time format.
    level     Set the root logger level to the specified level.
    stream    Use the specified stream to initialize the StreamHandler. Note
              that this argument is incompatible with 'filename' - if both
              are present, 'stream' is ignored.

>>> print logging.getLogger.__doc__

    Return a logger with the specified name, creating it if necessary.

    If no name is specified, return the root logger.
