You can configure the logging module by adding a custom format option like so

import logging

name = socket.hostname() 
logMessageFormat = '{}: %(levelname)s:%(message)s'.format(name)
logging.basicConfig(format=logMessageFormat, level=logging.DEBUG)

# Test new configuration
logger = logging.getLogger()
logger.info('Hello world')

# should print to the console
# : INFO:Hello world

You can read more about customizing the format of displayed messages here https://docs.python.org/3/howto/logging.html#changing-the-format-of-displayed-messages
