class MyClass:
     def __init__(self, name, job):
        self.logger = logging.getLogger(name)
        self.job = job


     def log(self, msg):
        self.logger.debug('#%d: %s' % (self.job, msg)


Then just call self.log('foo') whenever you want to log something.

If this isn't sufficient please describe what requirements you have that 
it doesn't meet.  (Subclassing Logger is certainly a simple way to do it 
though... in that case you would just pass the job number to the 
subclass when you construct it and it could do something like that above.
