Telegram bot is not sending messages

Question

I'm trying to execute this simple telegram bot but I get no output and I don't know what I'm doing wrong. This is the code:

from telegram import Update
from telegram.ext import Updater, CommandHandler, CallbackContext


def hello(update: Update, context: CallbackContext) -> None:
    update.message.reply_text(f'Hello {update.effective_user.first_name}')


updater = Updater('my_token')

updater.dispatcher.add_handler(hello)

updater.start_polling()
updater.idle()

If I run your code I do get an error: **TypeError: handler is not an instance of Handler** — 0stone0, May 27 '21 at 12:25

I think you missed some parameters in the add_handler function, so it should be like the following:

updater.dispatcher.add_handler(CommandHandler('hello', hello))
