The best logging package for Python!

1. Note that the default logging level is DEBUG in loguru and it is not allowed to change the logging level of an created logger object in loguru. You can refer to changing-the-level-of-an-existing-handler and Change level of default handler on ways to changing logging level in loguru.

   1. Remove the default logger (with logging level equals DEBUG) and add a new one with the desired logging level.
   2. Configure the environment variable LOGURU_LEVEL.

2. Log an exception using luguru and then throws an exception without logging redundant error messages.

    :::python
    def throw(_, error, message, *args, **kwargs):
        message = message.format(*args, **kwargs)
        logger.opt(depth=1).error(message)
        raise error(message)
   
    logger.__class__.throw = throw
   
    logger.throw(ValueError, "Something bad happened")
   
   

   Or if you do not care what kind of exception is thrown to user, you can use the following way which is more concise.

    :::python
    logger.error(message)
    sys.exit()

Set Logging Level¶

import sys
from loguru import logger

logger.remove()
logger.add(sys.stdout, level='INFO')
