Hello, thanks for the answer.

Yes, but I'm trying to use *TimedRotating*FileHandler, which makes the
fd of the logfile change in every rotation of the logfile. So the direct
approach of std[out|err] redirection to the logfile fd obtained from
the logger instance is unusable (it works fine with a simple file
handler). 
I'm looking into this because I really need rotating, because when
debugging is on, large amounts of data are logged, and because I like
the logging module approach in every aspect.

Also, may it be possible to derive the class and add a file-like write
method? Anyone using logging in this manner?


Cheers,
