I'm making a Python bot in VK for newsletters. and I have a question. Namely, why does it immediately turn off after starting?

Question

Python

import vk_api
from vk_api.utils import get_random_id

def main():
vk_session = vk_api.VKApi(token='token')
vk = vk_session.get_api()

user_list = [1, 2, 3, 4,]

for id in user_list:
vk .messages.send(
user_id=id,
random_id=get_random_id(),
message="text"
)

Answer 1

Because you, without reading a single tutorial, wrote code that does nothing.
