TG bot on python does not start, how to solve?

Question

Python

Already for the second week I can’t solve the problem with the tg parser bot with the exchange rate of the private bank
in the config file, I indicated the bot token.
https://pythonru.com/primery/python-telegram-bot here is a link to the article.

Who is an executor? dp?
