In order to configure the default logger for loguru Python’s library, e.g set a specific formatter or specify a different ‘sink’ (a.k.a output), you can access it this way:

from loguru import logger

config = {
    "handlers": [
        {
            "sink": sys.stdout,
            "format": "<level>{level: <8}</level>|<cyan>{name}</cyan>:<cyan>{function}</cyan>:<cyan>{line}</cyan> - <level>{message}</level>",
        }
    ]
}
logger.configure(**config)
