Question

Python

import telebot
from telebot import types
import random
token = '**'


bot = telebot.TeleBot(token)

@bot.message_handler(commands = ['start'])
def start(message):
  markup = types.ReplyKeyboardMarkup(resize_keyboard = True)
  item1 = types.KeyboardButton('Рандомное число')
  item2 = types.KeyboardButton('Офисный пк')
  item3 = types.KeyboardButton('Игровой пк')

  markup.add(item1, item2, item3)

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

  @bot.message_handler(content_types = ['text'])
  def bot_message(message):
    if message.text == 'Рандомное число':
      bot.send_message(message.chat.id, 'ваше число: ' +str(random.randint(0, 1000)))

    elif message.text == 'Офисный пк':
      markup = types.ReplyKeyboardMarkup(resize_keyboard = True)
      item1 = types.KeyboardButton('сборка')
      item2 = types.KeyboardButton('сборка такая то')
      back = types.KeyboardButton('назад')
      markup.add(item1, item2, back)
      bot.send_message(message.chat.id, 'Офисный пк', reply_markup = markup)

    elif message.text == 'Игровой пк':

    elif message.text == 'Назад':
      markup = types.ReplyKeyboardMarkup(resize_keyboard = True)
      item1 = types.KeyboardButton('Рандомное число')
      item2 = types.KeyboardButton('Офисный пк')
      item3 = types.KeyboardButton('Игровой пк')
      markup.add(item1, item2, item3)

      bot.polling(none_stop = True)

Answer 1

Try this design

if __name__ == '__main__':
  bot.polling(none_stop=True)

you don't need to do a tab.
