problem using logging module in python

[Manish Marathe]

Python Experts every where!!

I am having a problem using the logging utility in Python using the logging
module from the std. lib. I have written a class SPFLogger which actually
should be creating a new logger if one already does not exist. I have given
the class I wrote in the end. The problem I  am facing is:

I am creating 2/3 object of this class SPFLogger in 2/3 other classes of
mine having different logger name and the handler they will be using.
Although the logs are going in a single file which means the
logging.getLogger(name) function is getting the same logger which was
created earlier and not creating a new logger with new handler. Eventhough
the logs are going in a single file the loggers names used are different
which I am passing as an argument.

So for example if I do this first in the init method of class A:

obj1 = SPFLogger ("A", "A.log")
logger1 = obj.getLogger()
logger1.info("Message A") ----> Goes in A.log with logger name A

now class A calls class B so in the init method of class B I have:

obj2 = SPFLogger ("B", "B.log")
logger2 = obj.getLogger()
logger2.info("Message B") ----> still goes in A.log with logger name B ..

Is there something that needs to be done to handle this? Below is the code
for SPFLogger class

<!--------------------------------------------------
#!/usr/bin/env python
import logging
import logging.config

class SPFLogger:
class SPFLogger:
    """
       A logger instance will be generated using this class.

    def __init__(self, logger_type, handler_name):

Message\n"
                str +=

                f.write(str)
                f.flush()
                f.close()
            else:
                print "File does exists"

        return logger

if __name__=="__main__":
    spf = SPFLogger("Test", "test.log")
    testLogger = spf.getLogger()
    testLogger.debug("debug message")

    testLogger.warn("warn message")
    testLogger.error("error message")
    testLogger.critical("critical message")
