title: Getting the poll result from send_poll telegram bot with python
body: <p>It's a python code for a telegram bot to take a poll from the group chat. How can I get the final result of send_poll bot? I know the bot shows the result in the chat group but I need to save and use it for later. 
  For example, here I need the output to be like a or b.</p>
  
  <pre><code>    def poll(bot, update):
          options=['a','b']  
          bot.send_poll(update.message.chat_id, "please choose option a or 
          b:",options)
      updater.dispatcher.add_handler(CommandHandler('set', poll))  
      updater.start_polling()
  </code></pre>
