Yay! +1, especially if I can use them interchangeably. In my code, I usually like the log.debug() calls, but once in a while I have output that comes from something expecting a file-like API, and in that case, it would be nice to be able to pass in log.getFileObject(). Currently, I'm StringIO'ing it.

There's one wart in the implementation - to avoid printing out blank lines caused by the "\n" appended by print, we ignore messages which are == "\n". This works only because print does a separate write for the "\n". Can anyone see a problem with this approach?

What if the .log() method on loggers took an extra flag to suppress the newline or not, and the wrapper's .write() method passed the appropriate value? The default would be to include the extra newline so the .log() interface would be backward compatible.
