Python: How i implemented logging in my tool

#How I implemented logging in my tool:
#Requirement is to create a log file which has the name of BATCH JOB being executed, The environment being tested and The Date and Time information as the tool can be executed multiple times back to back
# INPUT_FILE_NAME is passed as second argument to the batch job
#  TEST_ENVIRONMENT is passed as third argument to the batch job

import time

import sys

import os

import datetime

import logging

# Split the input file name and take the first part of the name i.e. except .extension

log_file_name = 'logfile_' + os.path.splitext(str(sys.argv[1]))[0] + '_' + str(sys.argv[2]) + '_' + str(datetime.datetime.now().strftime("%Y_%m_%d_%H_%M_%S")) + '.log'

logger = logging.getLogger('Testing_Automation_Advanced')

logger.setLevel(logging.DEBUG)

# create file handler which logs even debug messages

fh = logging.FileHandler(log_file_name)

# LOG everything to the log file i.e. at DEBUG level

fh.setLevel(logging.DEBUG)

# create console handler with a higher log level

ch = logging.StreamHandler()

# Show only INFO+ level on the standard output i.e. screen

ch.setLevel(logging.INFO)

# create formatter and add it to the handlers

fhformatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
chformatter = logging.Formatter('%(asctime)s - %(message)s')
ch.setFormatter(chformatter)
fh.setFormatter(fhformatter)
# add the handlers to logger

logger.addHandler(ch)

logger.addHandler(fh)

#USE

logger.debug ('Logging at DEBUG level')

logger.info('Logging at INFO level')

# You can also encapsulate the logging directly and implement some STYLEs e.g.

def Print_Log_Style(log_text, style=None):

'''Puts the provided text in the list for the log file and also prints

it on the screen'''

if style.strip().upper() == 'TITLE':

multiplier = int(30-(len(log_text)/2))

logger.debug(60*'*')

logger.debug(' '*multiplier + log_text)

logger.debug(60*'*')

if style.strip().upper() == 'HEADER':

multiplier = int(15-(len(log_text)/2))

logger.debug(30*'-')

logger.debug(' '*multiplier + log_text)

logger.debug(30*'-')

if style.strip().upper() == 'SECTION':

multiplier = int(15-(len(log_text)/2))

logger.debug(30*'=')

logger.debug(' '*multiplier + log_text)

logger.debug(30*'=')

if style.strip().upper() is None:

logger.debug(log_text)
