Is it a bug?

[Darren Cui Liang]

Hi, there!

Now I am working around with the "logging" module. Here is the code:


 >>> import logging
 >>> log1=logging.getLogger("a")
 >>> log1.critical("msg")
No handlers could be found for logger "a"
 >>> logging.critical("msg")
CRITICAL:root:msg

Since every "logger" is under the "root logger", and if no handler is 
found for the logger, the message will be passed to upper level loggers, 
until the  root,
then why do I get the msg: No handlers could be found for logger "a"

Thanks in advance!
