Overridden Python logging methods to return passed message

log.py

#!/usr/bin/env python2
import logging

# get root logger
log = logging.getLogger()

# wrapper to return message after logging
def log_return(fn):
    def wrapper(msg, *args, **kwargs):
        fn(msg, *args, **kwargs)
        return msg
    return wrapper

# override logger methods
map(lambda fn: setattr(log, fn, log_return(getattr(log, fn))), 
    ('debug', 'info', 'warning', 'error', 'critical', 'exception'))

The default Python logging methods return void.

This leads to a somewhat verbose usage of an otherwise inline method:

msg = "Log message"
log.info(msg)
proc_msg(msg)

This snippet overrides the default methods to return the passed message:

proc_msg(log.info("Log Message"))
