Add a module-named logger to a class

# my_module.py

from autologging import logged


@logged
class MyClass:

    @staticmethod
    def my_staticmethod():
        MyClass.__log.info("my message")

    @classmethod
    def my_classmethod(cls):
        cls.__log.info("my message")

    def my_method(self):
        self.__log.info("my message")

>>> import logging, sys
>>> logging.basicConfig(
...     level=logging.INFO, stream=sys.stdout,
...     format="%(levelname)s:%(name)s:%(funcName)s:%(message)s")
>>> from my_module import MyClass
>>> MyClass.my_staticmethod()
INFO:my_module.MyClass:my_staticmethod:my message
>>> MyClass.my_classmethod()
INFO:my_module.MyClass:my_classmethod:my message
>>> my_obj = MyClass()
>>> my_obj.my_method()
INFO:my_module.MyClass:my_method:my message

Add a user-named logger to a class

# my_module.py

import logging
from autologging import logged


@logged(logging.getLogger("my.app"))
class MyClass:

    @staticmethod
    def my_staticmethod():
        MyClass.__log.info("my message")

    @classmethod
    def my_classmethod(cls):
        cls.__log.info("my message")

    def my_method(self):
        self.__log.info("my message")

>>> import logging, sys
>>> logging.basicConfig(
...     level=logging.INFO, stream=sys.stdout,
...     format="%(levelname)s:%(name)s:%(funcName)s:%(message)s")
>>> from my_module import MyClass
>>> MyClass.my_staticmethod()
INFO:my.app.MyClass:my_staticmethod:my message
>>> MyClass.my_classmethod()
INFO:my.app.MyClass:my_classmethod:my message
>>> my_obj = MyClass()
>>> my_obj.my_method()
INFO:my.app.MyClass:my_method:my message

Add a logger to a nested class

# my_module.py

from autologging import logged


@logged
class MyClass:

   @logged
   class _Nested:

      def __init__(self):
         self.__log.info("my message")

   def my_method(self):
      self.__log.info("my message")
      nested = self._Nested()

>>> import logging, sys
>>> logging.basicConfig(
...     level=logging.INFO, stream=sys.stdout,
...     format="%(levelname)s:%(name)s:%(funcName)s:%(message)s")
>>> from my_module import MyClass
>>> my_obj = MyClass()
>>> my_obj.my_method()
INFO:my_module.MyClass:my_method:my message
INFO:my_module.MyClass._Nested:__init__:my message

Add a module-named logger to a function

# my_module.py

from autologging import logged


@logged
def my_function():
    my_function._log.info("my message")

>>> import logging, sys
>>> logging.basicConfig(
...     level=logging.INFO, stream=sys.stdout,
...     format="%(levelname)s:%(name)s:%(funcName)s:%(message)s")
>>> from my_module import my_function
>>> my_function()
INFO:my_module:my_function:my message

Add a user-named logger to a function

# my_module.py

import logging
from autologging import logged


@logged(logging.getLogger("my.app"))
def my_function():
    my_function._log.info("my message")

>>> import logging, sys
>>> logging.basicConfig(
...     level=logging.INFO, stream=sys.stdout,
...     format="%(levelname)s:%(name)s:%(funcName)s:%(message)s")
>>> from my_module import my_function
>>> my_function()
INFO:my.app:my_function:my message

Add a logger to a nested function

# my_module.py

from autologging import logged

@logged
def my_function():
   @logged
   def nested_function():
      nested_function._log.info("my message")
   my_function._log.info("my message")
   nested_function()

>>> import logging, sys
>>> logging.basicConfig(
...     level=logging.INFO, stream=sys.stdout,
...     format="%(levelname)s:%(name)s:%(funcName)s:%(message)s")
>>> from my_module import my_function
>>> my_function()
INFO:my_module:my_function:my message
INFO:my_module:nested_function:my message
