The logging module doesn't allow you to update its config. You're
supposed to configure all the options you want in a single call to
basicConfig (or one of the other config methods for a different way to
configure logging)
>>> import logging
>>>
logging.basicConfig(filename='example.log',level=logging.DEBUG,format='%(asctime)s;%(levelname)s:%(message)s')
>>> logging.info('Message2')
>>> logging.warning('Message3')
produces this
2018-08-13 12:52:03,330;INFO:Message2
2018-08-13 12:52:04,231;WARNING:Message3
