How to make a script to remove all people from a channel in tg?

Question

Python

We need a script that will remove all people from the channel using a userbot.
I did this:

api_id = 'api'
api_hash = 'hash'
import time
from pyrogram.errors import FloodWait
from pyrogram import Client

chat = 'chat'

with Client("myacc", api_id, api_hash) as app:
    for u in app.get_chat_members(chat):
        with app:
            try:
                app.kick_chat_member(chat, u.id, int(time.time() + 60))
            except FloodWait as e:
                time.sleep(e.x)

but it gives an error:

raise ConnectionError("Client is already connected")
ConnectionError: Client is already connected
