Telethon , telegram , join telegram channels from a list

#channel joiner.md

Here is an example of .env file you need to use:

Make sure to have telethon and python-dotenv installed.

join_channels.py

# make sure to have telethon and python-dotenv installed
# create a file called .env in the current directory from where you are running the script
# put API_ID and  API_HASH in the .env file in the following format
# VARIABLE=VALUE


from telethon.sync import TelegramClient
from telethon.tl.functions.channels import JoinChannelRequest
from telethon.errors.rpcerrorlist import FloodWaitError

from dotenv import load_dotenv
import os
import asyncio

load_dotenv()
API_ID = os.getenv('API_ID')
API_HASH = os.getenv('API_HASH')


CHANNELS = ['a', 'b', 'c']  # the channels you want to join


async def main():
    async with TelegramClient('tg_session', API_ID, API_HASH) as client:
        for channel in CHANNELS:
            try:
                await client(JoinChannelRequest(channel))
            except FloodWaitError as fwe:
                print(f'Waiting for {fwe}')
                await asyncio.sleep(delay=fwe.seconds)
            except Exception as err:
                print(f"Encountered an error while joining {channel}\n{err}")

asyncio.run(main())

hi, @MaksGruv52, I have updated the code in the gist. Please try again.

Put a few invalid channels, and some valid channels, on encountering an error, it will not stop. It will print the error on the terminal, and continue with the next channel.

Hi, thank you very much! I'll start testing it now!

How to add a group interval? You will soon be prompted "waiting for a wait of * * * * seconds is required"

hy man! im trying to run your code, but i always got an error message:

The API access for bot users is restricted. The method you tried to invoke cannot be executed as a bot (caused by JoinChannelRequest)
Encountered an error while joining @cryptolinksgroup

at point it asked my phone, or bot token. my phone have a token access? i thought only api id, and hash have.

hi, @aahnik! how do I make it so that the cat can access channels via private links?
