Pass A Counter To Every Python Logging Method

The python logging method can be set to print the time of each event. However if I am running a simulation with its own time variable can that be used in the logger? The logging F

Solution 1:

You could use a logging.Filter:

import logging

class ContextFilter(logging.Filter):
    def filter(self, record):
        record.count = counter
        return True

logging.basicConfig(
    level = logging.DEBUG,
    format = '%(levelname)-8s: %(count)s: %(message)s')
logger = logging.getLogger(__name__)
logger.addFilter(ContextFilter())

counter = 5
logger.debug('First Event')
counter += 2
logger.warning('Second Event')

yields

DEBUG   : 5: First Event
WARNING : 7: Second Event
