How to solve the problem with the simplest bot in Python?

Question

Python

import telebot

bot = telebot.TeleBot("TOKEN")

@bot.message_handler(commands=['start', 'help'])
def send_welcome(message):
  bot.reply_to(message, "Howdy, how are you doing?")

@bot.message_handler(func=lambda message: True)
def echo_all(message):
  bot.reply_to(message, message.text)

bot.polling()

I wrote a bot as indicated in the instructions in the module description at: https://pypi.org/project/pyTelegramBotAPI/#getting... , but it does not work.
Please help

Answer 1

I solved the problem myself, there was an error in the token. Through botFather, I did a revoke, inserted a new token, and everything started

Answer 2

Have you installed telebot as written on PyPI?
Try some example from their GitHub or official site.
