Python logging multiple files using the same logger

Question

This is my scenario: I want to log my_module\'s activity. This needs to be done, depending on the method executed (let\'s say, INPUT and OUTPUT), to two different files.

Answer 1

You should instantiate an Handler for each destination you want to send your log to, then add the 2 handlers to your logger. The following should work (didn't test it though):

logger = logging.getLogger()
handler1 = logging.TimedRotatingFileHandler()
handler2 = logging.TimedRotatingFileHandler()
logger.addHandler(handler1)
logger.addHandler(handler2)

Of course add all your configuration and formatting options you may need. Basically it is just to show you that when you instantiate the logging handler you can add it to the logger. From that moment on, your log records will be emitted to every handler added to the logger.
