[FIXED] how to run pyrogram userbot with multiple user accounts using thread

Issue

I am coding a userbot in pyrogram but I want to run multiple Clients with different telegram account but I am stuck here. I want to run userbot on multiple accounts using one script if I will run it separately then I have to host it so many time I want to host it for one time and run for every account I have.
I think this will help to understand what I am saying.

from pyrogram import Client, filters, handlers, idle
import threading
from pyrogram.handlers import MessageHandler

app1 = Client(
    session, api_hash, api_id)


app2 = Client(session,
              api_hash, api_id)


accounts = [app1, app2]


async def handlngmessage(client, message):
    print(message)
    print("\nstarted ")
    await client.send_message("me", "recived")


def runner(c):
    c.run()


for ac in accounts:
    ac.add_handler(handlers.MessageHandler(unmutedtest))
    t = threading.Thread(target=runner, args=(ac,))
    t.start()
    t.join()

When I run this I am just getting error

Output:

Solution

With Pyrogram you don't need to use Threading. The internal code is already entirely asynchronous and you can just start the clients one after another, then call Client.idle() to keep them all "alive".

from pyrogram import Client

app1 = Client("first account")
app2 = Client("second account")

# You can either stack decorators ...
@app1.on_message()
@app2.on_message()
async def m_func(_, message):
    pass

# ... or use multiple add_handler calls
app1.add_handler(MessageHandler(m_func))
app2.add_handler(MessageHandler(m_func))

# Then start all Clients and call idle() to keep them running
app1.start()
app2.start()
Client.idle()
app1.stop()
app2.stop()
