How to parse the site (train time) and make it activation by buttons in the VK bot?

Question

Python

I would like to understand how to send by button, the time of trains in the VK bot, but I can’t find a solution

Answer 1

Parsing the schedule each time the bot is requested is too resource intensive. It is better to prepare a sample in advance. For example, you can make a cron-job that will collect the schedule every n-minutes/hours and place it in a database/file, and then send it in response to a request to the bot.
