random import randint
from telethon.tl import types

api_id = 0
api_hash = 'a'
bot_token = 'a'
client = TelegramClient('session', api_id, api_hash)
client.start(bot_token=bot_token)

@client.on(events.NewMessage(pattern=r"^img$"))
async def my_event_handler(event):
url = f'https://t.me/channels/{randint(2, 3)}'
