This is easy enough to do, I posted about it in 2009 here:

http://plumberjack.blogspot.co.uk/2009/09/how-to-treat-logger-like-output-stream.html

Basically, something like

class LoggerWriter(object):
    def __init__(self, logger, level):
        self.logger = logger
        self.level = level

    def write(self, message):
        if message != '\n':
            self.logger.log(self.level, message)

    def flush(self):
        pass

I'm not sure something like this really needs to be in the stdlib.

Loggers shouldn't have a method with a print-like signature, since it's Handlers that are concerned with output destinations such as streams.
