Logger From Config File
You can configure logging using the module and class functions or by creating a config file or a dictionary and loading it using
dictConfig() respectively. These are useful in case you want to change your logging configuration in a running application.
Here’s an example file configuration:
[loggers] keys=root,sampleLogger [handlers] keys=consoleHandler [formatters] keys=sampleFormatter [logger_root] level=DEBUG handlers=consoleHandler [logger_sampleLogger] level=DEBUG handlers=consoleHandler qualname=sampleLogger propagate=0 [handler_consoleHandler] class=StreamHandler level=DEBUG formatter=sampleFormatter args=(sys.stdout,) [formatter_sampleFormatter] format=%(asctime)s - %(name)s - %(levelname)s - %(message)s
In the above file, there are two loggers, one handler, and one formatter. After their names are defined, they are configured by adding the words logger, handler, and formatter before their names separated by an underscore.
