How to check if an account with the telethon library is banned?

Question

Python

this_client = TelegramClient(phone_number, api_id, api_hash)
        this_client.connect() 
        if not this_client.is_user_authorized():
            try:
                this_client.send_code_request(phone_number)
            except telethon.errors.rpc_error_list.PhoneNumberBannedError:
                print("Phone number is banned.")
                this_client.disconnect()

Here is the code that doesn't work. Are there other possibilities?
