Trying to do some stuff with telebot + telethon.

-------------------- Code --------------------

      FILE: All.py

      if bot.get_chat_member(message.chat.id, message.from_user.id).status != 'member':
         f = open("assets/database/" + str(message.chat.id) + '.txt', 'w+')
         invite = bot.export_chat_invite_link(message.chat.id)
         bot.get_chat(message.chat.id)
         f.close()
         chat_id = str(message.chat.id)
         f = open("assets/transfer/" + str(message.chat.id) + '.txt', 'w+')
         f.write(str(invite) + " " + str(message.from_user.id))
         f.close()
         a = bot.send_message(message.chat.id, message.chat.id)
         mess_id = a.message_id
         bot.delete_message(message.chat.id, mess_id)
         GetMember = bot.get_chat_member(message.chat.id, message.from_user.id)
         f = open("assets/transfer/chat_id.txt", 'w+')
         f.write(str(message.chat.id))
         f.close()
         import Test.py
         bot.send_message(message.chat.id, 'Запись проведена успешно. Спасибо!')

           FILE Test.py

client = TelegramClient('Bot-Helper', api_id, api_hash).start(bot_token=bot_token)

ch = open('assets/transfer/chat_id.txt', 'r+')
chat_id = ch.readline()
f = open('assets/transfer/' + str(chat_id) + '.txt', 'r+')
fn = open('assets/database/' + str(chat_id) + '.txt', 'w+')
stroka = f.readline().split()
f.close()
parti = client.get_participants(str(stroka[0]))
for x in parti:
   if x.bot == False:
      fn.write(str(x.id) + " ")
   else:
      pass
fn.close()
