Make small change to python web scrape script

I have a python script it reads from csv file and refreshes a link. if the key word match it will email me. I need to make 3 small updates to it. 1. I want to be able to add "avoid words", if the string contacts any of these words then do not trigger email notification. 2. for each result it looks at it says the result so doesn't send the same email to me again. 3. sometimes the text contains special characters, need to add in Try and Except to handle this and skip it. it uses the following libraries import time import os import json import csv import random import requests import email import smtplib import datetime import string import re from [login to view URL] import urlencode, urljoin, urlparse, parse_qs from difflib import SequenceMatcher from [login to view URL] import CookieJar import html as HTMLParser from playsound import playsound Please only offer on this task if you know how to program in python and are fairly familiar with python programming.
