bot_token = 'MY Token'
updater = Updater(token=bot_token, use_context=True)
dispatcher = updater.dispatcher


# /start
def start(update, context):
context.bot.send_message(chat_id=update.effective_chat.id, text="hi, bot joined at group.", reply_markup=get_custom_keyboard())

# get time
def get_time(update, context):
import datetime
current_time = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')
context.bot.send_message(chat_id=update.effective_chat.id, text=f"current time is {current_time}", reply_markup=get_custom_keyboard())

# message handler
def handle_message(update, context):
user_message = update.message.text
if user_message == 'time':
get_time(update, context)
else:
context.bot.send_message(chat_id=update.effective_chat.id, text=f"받은 메시지: {user_message}", reply_markup=get_custom_keyboard())

# custom keyboard
def get_custom_keyboard():
custom_keyboard = [
[KeyboardButton("time"), KeyboardButton("one option")],
[KeyboardButton("two option")]
]
return ReplyKeyboardMarkup(custom_keyboard, resize_keyboard=True)

# /start
start_handler = CommandHandler('start', start)
dispatcher.add_handler(start_handler)

# message handler
message_handler = MessageHandler(Filters.text & ~Filters.command, handle_message)
dispatcher.add_handler(message_handler)


updater.start_polling()
updater.idle()
