Right. Thanks a lot!!!

Now for the second part, any idea why logging.config.fileConfig doesn't work?

Now the logging.conf looks like this:

[formatters]
keys: detailed

[handlers]
keys: console,file

[loggers]
keys: root

[formatter_detailed]
format: %(name)s:%(levelname)s %(module)s:%(lineno)d:  %(message)s

[handler_console]
class: StreamHandler
args: []
formatter: detailed

[handler_file]
class=FileHandler
formatter=detailed
args=('output.log', 'w')
filename=output.log
mode=w

[logger_root]
level: INFO
handlers: file
