如何使用python-telegram-bot制作类似示例的按钮？

pip install python-telegram-bot

from telegram import InlineKeyboardButton, InlineKeyboardMarkup
from telegram.ext import Updater, CommandHandler, CallbackQueryHandler

def start(update, context):
    keyboard = [
        [InlineKeyboardButton("按钮1", callback_data='button1')],
        [InlineKeyboardButton("按钮2", callback_data='button2')],
    ]
    reply_markup = InlineKeyboardMarkup(keyboard)
    update.message.reply_text('请选择一个按钮：', reply_markup=reply_markup)

def button(update, context):
    query = update.callback_query
    query.answer()
    if query.data == 'button1':
        query.edit_message_text(text="你点击了按钮1！")
    elif query.data == 'button2':
        query.edit_message_text(text="你点击了按钮2！")

updater = Updater('YOUR_TOKEN', use_context=True)
dispatcher = updater.dispatcher
dispatcher.add_handler(CommandHandler('start', start))
dispatcher.add_handler(CallbackQueryHandler(button))

updater.start_polling()
