Naming Python loggers

Question

In Django, I\'ve got loggers all over the place, currently with hard-coded names.

For module-level logging (i.e., in a module of view functions) I have the urge to d

Answer 1

I typically don't use or find a need for class-level loggers, but I keep my modules at a few classes at most. A simple:

import logging
LOG = logging.getLogger(__name__)

At the top of the module and subsequent:

LOG.info('Spam and eggs are tasty!')

from anywhere in the file typically gets me to where I want to be. This avoids the need for self.log all over the place, which tends to bother me from both a put-it-in-every-class perspective and makes me 5 characters closer to 79 character lines that fit.

You could always use a pseudo-class-decorator:

>>> import logging
>>> class Foo(object):
...     def __init__(self):
...             self.log.info('Meh')
... 
>>> def logged_class(cls):
...     cls.log = logging.getLogger('{0}.{1}'.format(__name__, cls.__name__))
... 
>>> logged_class(Foo)
>>> logging.basicConfig(level=logging.DEBUG)
>>> f = Foo()
INFO:__main__.Foo:Meh
