How to make a check for new news so that the program understands that there is new news and immediately parses it?

Question

Python

I made a telegram bot that parses football matches and wanted to add news about football. you need to do so when a new news appears on the site, you should parse it to all users of the bot!

Answer 1

Option 1. The site is yours: create an event and pull it in the bot when adding news
Option 2. The site is not yours (which is most likely): use crone/ schedule , get the news and check, if there are new ones, then parse them and send them to all users, for example (consider - pseudocode):

import schedule
import time

my_news = [] #массив новостей/любая другая структура/или что-то с БД

def job():
    #запрос за новостями

def check_new():
    #проверяем, есть ли тут новые новости, если есть, то отправляем юзерам

schedule.every(10).minutes.do(job) #отправлять запрос каждые 10 минут
schedule.every(15).minutes.do(check_new)

while 1:
    schedule.run_pending()
    time.sleep(1)
