This is the code of the Telegram bot I use in my lectures.

It needs an argument: it is a text file containing the token of the bot.
(it is the long exa number provided by the BotFather when the new bot is registered)

The bot shows all the messages it receives.

It is possible to do simple ballots:
/vote cast a vote
e.g.

/vote yes

to count the votes simply send

/count

here is the code:
