Python dictconfig不记录INFO级别的消息

Question

I have python code that looks like this:

import logging
import logging.config

LOG_SETTINGS = {
    'version': 1,

    'formatters': {
        'simple': {
            'format': '%(levelname)s: %(message)s'
        },
    },

    'handlers': {
        'file_handler': {
            'class': 'logging.FileHandler',
            'filename': 'example-dict-config-log.log',
            'level': 'INFO',
            'formatter': 'simple',
     },
    'console': {
        'class': 'logging.StreamHandler',
        'formatter': 'simple',
        'level': 'ERROR'
        }
    },

    'loggers': {
        __name__: {
            'handlers': ('file_handler', 'console',)
        }
    }
}


logging.config.dictConfig(LOG_SETTINGS)

logger = logging.getLogger(__name__)


logger.error('error messages should go to stderr and file')
logger.info("info messages should go to file")

The dict configuration file looks ok to me, but code does not seem to be logging the INFO level message. What did I do wrong?

Answer 1

I realized that my logger has a default level of WARNING , and thus will not be able to log INFO messages (whose level number is lower than WARNING ). so in the __name__ logger, I added 'level': 'INFO' and that did it.
