What is "@" used for in front of variables in Python?

Question

Python

Hello, I recently started studying the topic of creating telegram bots, and in all the guides, the "dp" variable, which is an instance of the Dispatcher class, is preceded by the "@" symbol. I do not like to just copy someone else's code, so I would like to know what it is used for in this and other cases.

Code snippet where this symbol is used:

# tg bot init
api = Bot(token = config.TG_API_TOKEN)
dp = Dispatcher(api)

@dp.message_handler()
async def echo(message : types.Message) :
    await message.answer(message.text)

These crooks in videos about bots themselves studied this issue, but they don’t teach you, but force you to repeat stupid actions like monkeys. So you need it, ignoramuses.
