Бот под видом стороннего клиента,
from telethon import TelegramClient, sync
from turtle import *
app_id = ""
app_hash = ""
client = TelegramClient('hellobot', app_id, app_hash)
noobie1 = client.get_participants('chatname')
def send_noobie():
noobie = client.get_participants('chat_name')
for username in set(noobie).diference(noobie1):
client.send_message(username, 'Hello')
noobie = list(noobie1)
def run():
ontimer(send_noobie(), 600000)
while True:
run()
client.start()
client.run_until_disconnect()
Так сработает?
