Throughout this tutorial, we will guide you through each step, ensuring a thorough understanding of the concept.


# Import necessary libraries
from telethon import TelegramClient

# Your credentials here
api_id = 'your_api_id'
api_hash = 'your_api_hash'

# Create a client object
client = TelegramClient('session_name', api_id, api_hash)

async def main():
    # Start the client
    await client.start()

    # Scrape messages from a specific chat or channel
    async for message in client.iter_messages('chat_or_channel_username'):

if __name__ == '__main__':
    import asyncio
