Chat GPT answer to 'write a telegram bot'

telegram_bot.py

import logging
import telegram
from telegram.ext import Updater, CommandHandler, MessageHandler, Filters

# Enable logging
logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',
                    level=logging.INFO)

logger = logging.getLogger(__name__)


# Define a function to handle the /start command
def start(update, context):
    update.message.reply_text('Hi! Use /echo to send a message that I will repeat back to you.')


# Define a function to handle the /echo command
def echo(update, context):
    update.message.reply_text(update.message.text)


# Define a function to handle all other messages
def unknown(update, context):
    update.message.reply_text('Sorry, I don't understand that command.')


# Create the Updater and pass it your bot's token
updater = Updater('YOUR_BOT_TOKEN', use_context=True)

# Get the dispatcher to register handlers
dispatcher = updater.dispatcher

# Add the start command handler
dispatcher.add_handler(CommandHandler('start', start))

# Add the echo command handler
dispatcher.add_handler(CommandHandler('echo', echo))

# Add the unknown command handler
dispatcher.add_handler(MessageHandler(Filters.command, unknown))

# Start the bot
updater.start_polling()

# Run the bot until you press Ctrl-C or the process receives SIGINT,
# SIGTERM or SIGABRT. This should be used most of the time, since
# start_polling() is non-blocking and will stop the bot gracefully.
updater.idle()
