Python 3.x 如何在电报机器人上添加自定义键盘？

这是我的电报号码：

import time, datetime
import telepot
from telepot.loop import MessageLoop

now = datetime.datetime.now()

def action(msg):
    chat_id = msg['chat']['id']
    command = msg['text']

    print('Received: %s' % command)

    if command == '/start':
        telegram_bot.sendMessage (chat_id, str("Hi!"))
        telegram_bot.sendMessage(chat_id, str(now.hour)+str(":")+str(now.minute))
    elif command == 'Time':
        telegram_bot.sendMessage(chat_id, str(now.hour)+str(":")+str(now.minute))
    elif command == 'Logo':
        telegram_bot.sendPhoto (chat_id, photo = "https://i.pinimg.com/avatars/circuitdigest_1464122100_280.jpg")
    elif command == 'File':
        telegram_bot.sendDocument(chat_id, document=open('/home/pi/sendbot.py'))
    elif command == 'Audio':
        telegram_bot.sendAudio(chat_id, audio=open('/home/pi/test.mp3'))

telegram_bot = telepot.Bot('MY-BOT-TOKEN')
print((telegram_bot.getMe()))

MessageLoop(telegram_bot, action).run_as_thread()
print('Up and Running....')

while 1:
    time.sleep(10)

我想为这个机器人添加一个自定义键盘，它将有4个按钮，分别名为

时间

，

徽标

，

文件

和

音频

例如，如果我点击

Time

按钮而不是键入“Time”，它会告诉我时间。

如果我点击

Logo

按钮而不是键入它，它将向我发送图片

这本书中有一些很好的例子。请看他们

...
    markup = ReplyKeyboardMarkup(keyboard=[['Time', KeyboardButton(text='Logo')],["File", "Audio"]])
    if command == '/start':
        telegram_bot.sendMessage (chat_id, str("Hi! Which one do you want? choose from the below keyboard buttons."), reply_markup=markup)
        telegram_bot.sendMessage(chat_id, str(now.hour)+str(":")+str(now.minute))
...

我已经添加了那些得到错误的行。要导入什么？您可能需要导入两件东西：from telepot.namedtuple import ReplyKeyboardMarkup、KeyboardButton
