I am working on a Python library with multiple packages and a main routine outside these packages. I have set up a logger to log to the standard output and a log file using a configuration file as suggested in the question Using Python logging in multiple modules. When I put the main routine (main.py) into a package (mypackage), everything works as intended. However, if I start the main routine in the project's root folder, the code breaks (ConfigParser.NoSectionError: No section: 'formatters').
Is there a suggested solution for this problem?
Here is a minimal working example:
. ├── logging.conf ├── main.py ├── mypackage │ ├── __init__.py │ └── mymodule.py └── smodels.log logging.conf:
[loggers] keys=root [handlers] keys=consoleHandler,fileHandler [formatters] keys=consoleFormatter,fileFormatter [logger_root] level=DEBUG handlers=consoleHandler,fileHandler [handler_consoleHandler] class=StreamHandler level=DEBUG formatter=consoleFormatter args=(sys.stdout,) [handler_fileHandler] class=FileHandler level=INFO formatter=fileFormatter args=('smodels.log',) [formatter_consoleFormatter] format=%(asctime)-8s.%(msecs)03d %(levelname)-8s %(name)s:%(lineno)-3s %(message)s datefmt=%H:%M:%S [formatter_fileFormatter] format=%(asctime)-16s %(levelname)-8s %(filename)-s:%(lineno)-3s %(message)s datefmt=%Y-%m-%d %H:%M main.py:
#!/usr/bin/env python from mypackage import mymodule import logging logger = logging.getLogger(__name__) def main(): logger.debug('This is a debug message.') logger.info('This is an info message.') mymodule.test() if __name__=='__main__': main() __init__.py:
import mymodule import logging.config logging.config.fileConfig('../logging.conf',disable_existing_loggers=False) logger = logging.getLogger(__name__) mymodule.py:
import logging logger = logging.getLogger(__name__) def test(): logger.debug('Module debug.') logger.info('Module info.')
