Short example for instantiating logging in python

logging_python.py

# logging_example.py
"""
With the logging module imported, you can use something called a “logger” to log messages that you want to see. 
By default, there are 5 standard levels indicating the severity of events. 
Each has a corresponding method that can be used to log events at that level of severity. 
The defined levels, in order of increasing severity, are the following:
  - DEBUG
  - INFO
  - WARNING
  - ERROR
  - CRITICAL

import logging

# Standard logger
logging.basicConfig(level=logging.DEBUG)
logging.debug('This will get logged')

# Create a custom logger
logger = logging.getLogger(__name__)

# Create handlers
c_handler = logging.StreamHandler()
f_handler = logging.FileHandler('file.log')
c_handler.setLevel(logging.WARNING)
f_handler.setLevel(logging.ERROR)

# Create formatters and add it to handlers
c_format = logging.Formatter('%(name)s - %(levelname)s - %(message)s')
f_format = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
c_handler.setFormatter(c_format)
f_handler.setFormatter(f_format)

# Add handlers to the logger
logger.addHandler(c_handler)
logger.addHandler(f_handler)

logger.warning('This is a warning')
logger.error('This is an error')
