How to optimize my telegram bot written in Python?

Question

Python

I wrote a fairly simple bot that provides information or additional choices based on the user's request. It works well and does its job, however I was wondering how can I optimize my code and use telebot better? Currently, the main action happens in the callback query handler, and something tells me that I'm lacking efficiency (for example, when I try to create more user select forks). Below is the code, simplified for demonstration purposes:

import telebot
from telebot import types

token = bottoken

bot = telebot.TeleBot(token)

@bot.message_handler(commands=['start'])
def welcome(message):

  # here i give the main choice that is always visible to the user

  markup = types.ReplyKeyboardMarkup(resize_keyboard=False)
  item1 = types.KeyboardButton("Button1")
  item2 = types.KeyboardButton("Button2")

  markup.add(item1, item2)

  bot.send_message(message.chat.id, "Welcome message".format(message.from_user, bot.get_me()),
    parse_mode='html', reply_markup=markup)


@bot.message_handler(content_types=['text'])
def main_choice(message):

  # here i develop each of the main choices and redirect to the callback handler

  if message.text == 'Button1':

    # Forward to callback handler

      markup = types.InlineKeyboardMarkup()
      item1 = types.InlineKeyboardButton("Yes", callback_data = 'demo_yes')
      item2 = types.InlineKeyboardButton("No", callback_data = 'demo_no')

      markup.add(item1, item2)

      bot.send_message(message.chat.id, 'Some text', reply_markup=markup)


  elif message.text == 'Button2':

    # some logic

  else :
    bot.send_message(message.chat.id, 'Sorry, i dont understand. You can use /help to check how i work')


@bot.callback_query_handler(func=lambda call: True)
def tempo(call):

  # here a handle the queries launched both by main buttons and the inline keyboard 


  if call.data == "demo_yes":

    keyboard = types.InlineKeyboardMarkup()
    item1 = types.InlineKeyboardButton("Text1", callback_data = 'call1')
    item2 = types.InlineKeyboardButton("Text2", callback_data = 'call2')
    keyboard.add(item1,item2)

    bot.send_message(call.message.chat.id, 'message', reply_markup = keyboard)

  elif call.data == "demo_no":

    kkeyboard = types.InlineKeyboardMarkup()
    item1 = types.InlineKeyboardButton("Text3", callback_data = 'call3')
    item2 = types.InlineKeyboardButton("Text4", callback_data = 'call4')
    keyboard.add(item1,item2)

    bot.send_message(call.message.chat.id, 'message', reply_markup = keyboard)

  if call.data == "call1":

    keyboard = types.InlineKeyboardMarkup()
    item1 = types.InlineKeyboardButton("Text5", callback_data = 'another_call1')
    item2 = types.InlineKeyboardButton("Text6", callback_data = 'another_call2')
    keyboard.add(item1,item2)

    bot.send_message(call.message.chat.id, 'message', reply_markup = keyboard)

  elif call.data == "call2":

    kkeyboard = types.InlineKeyboardMarkup()
    item1 = types.InlineKeyboardButton("Text7", callback_data = 'another_call3')
    item2 = types.InlineKeyboardButton("Text8", callback_data = 'another_call4')
    keyboard.add(item1,item2)

    bot.send_message(call.message.chat.id, 'message', reply_markup = keyboard)

Answer 1

Well, at first glance, you can just scatter at least three files:
1.py

import telebot
from telebot import types
token = bottoken
bot = telebot.TeleBot(token)
bot.polling()

2.py

#Все хендлеры

@bot.message_handler(commands=['start'])
def welcome(message):

2.py

#Все коллбеки без elif а нормально читаемые

@bot.callback_query_handler(func=lambda call: call.data == '7')
def seven(call):
    bot.send_message(call.message.chat.id,text = 'seven')

@bot.callback_query_handler(func=lambda call: call.data == '1')
def one(call):
    bot.send_message(call.message.chat.id,text = 'one')
