Asynchronous function in telegram bot

Question

From understanding basics of async/await I learned that time.sleep() is a blocking function, which freezes the execution. I tried to check it in this simple message_handler while creating a telegram bot.

import telebot
from time import sleep

token = '...'
bot = telebot.TeleBot(token)

@bot.message_handler(commands=['test'])
def test(message):
    bot.send_message(message.chat.id, 'Hello')
    sleep(5)
    bot.send_message(message.chat.id, 'World')

if __name__ == '__main__':
bot.infinity_polling()

A /test command was sent from two devices with a little interval (<5s). I expected the program to send a message 'Hello' to the first device, freeze for 5 seconds and then send 'World', and only after that do the same with the second device. But instead both devices were treated simultaneously.

In this case I cannot understand the process. How does the program respond immediately to the second device, if it was frozen by time.sleep() after responding to the first one?

Answer 1

import asyncio

async def test(message): # use this as your function
    await asyncio.sleep() # replace time.sleep()
