Как в питоне получить данные после @ в строке?

req = body.lower()
                poll = vkUser.method("polls.create",
                {
                "question": "test",
                "add_answers": json.dumps(["yes","no"])
                })
                poll_id = poll["id"]
                attachmentPoll = "poll1_" + str(poll_id)
                vk.method("messages.send",
                {
                "peer_id": id,
                "random_id": random.randint(1, 2147483647),
                "message": req.split('@')[1],
                "attachment": attachmentPoll
                })
