Background

Needed a way to log messages for my script

Problem

The logging needed to do the things below:

Log messages to a file and also steaming

Two different functions had to log to two different log files.

Solution

import logging
TS = datetime.now().strftime('%Y%m%d_%H%M%S')
formatter = logging.Formatter(
  '%(asctime)s, %(levelname)s: %(message)s')

def setup_logger(name, log_file, level=logging.INFO):
    file_handler = logging.FileHandler(log_file)
    file_handler.setFormatter(formatter)

    stream_handler = logging.StreamHandler()
    stream_handler.setFormatter(formatter)

    logger = logging.getLogger(name)
    logger.setLevel(level)
    logger.addHandler(file_handler)
    logger.addHandler(stream_handler)
    return logger

log_level = logging.DEBUG
logger = setup_logger('exmaple_log_name_1', f'exmaple_log_file-{TS}.log', log_level)
logger.info(f'Example Info Log')

Result
