why does one of my IF statements not work! on python

this is my code, it works perfectly except last if statement. i want to when the list members become 0 the bot send this message: "No One"

this code work perfectly,when the list reaches 2 bot say: fix. but when it reaches 0 it doesnt say anything!

 from telegram.ext import Updater , CommandHandler , Filters , 
 CommandHandler , MessageHandler
 from telegram import MessageEntity
 from telegram import ParseMode , InputTextMessageContent

 updater = Updater("989165404:AAF8DEjyunwrb88-1G8w62cGItzXj1J618g")

list = []
wordsm=["m"]
wordsn=["n"]

def msg_filter(bot , update):

    if any (i in update.message.text for i in wordsm):
        list.append("{}".format(update.message.from_user.first_name))
        bot.send_message(chat_id = update.message.chat_id , text = 
        "\n".join(list))

       if len(list)==2:
        bot.send_message(chat_id = update.message.chat_id , text = "FiX!")


         if any (j in update.message.text for j in wordsn):
         list.remove("{}".format(update.message.from_user.first_name))
          bot.send_message(chat_id = update.message.chat_id , text = 
         "\n".join(list))


         if len(list)==0:
        bot.send_message(chat_id = update.message.chat_id , text = "No 
        One")

       print(list)
       print(len(list))

       updater.dispatcher.add_handler(MessageHandler(Filters.text 
       ,msg_filter ))
       updater.start_polling()
