How to send a message from a bot to multiple users at the same time?

Question

Python

Hi, I'm making a mailing bot, and I can't figure out how to send a message to several users at the same time! I have id of all users! I send via
bot.send_message

Answer 1

ids = open('ids.txt', 'r')
for id in ids:
    bot.send_message(chat_id=id, text="Test text")

Enter the ID in the text file ids.txt, each on a new line.
You can run it in several threads, only then you need to add a condition so that each of the threads processes a certain number of IDs in order to avoid duplication of sent messages.
