如何在电报机器人中每行添加1个按钮？

from telegram import InlineKeyboardButton, InlineKeyboardMarkup

button1 = InlineKeyboardButton("按钮1", callback_data='button1')
button2 = InlineKeyboardButton("按钮2", callback_data='button2')
button3 = InlineKeyboardButton("按钮3", callback_data='button3')

keyboard = [[button1], [button2], [button3]]
reply_markup = InlineKeyboardMarkup(keyboard)

update.message.reply_text('请点击以下按钮：', reply_markup=reply_markup)

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

def start(update, context):
    button1 = InlineKeyboardButton("按钮1", callback_data='button1')
    button2 = InlineKeyboardButton("按钮2", callback_data='button2')
    button3 = InlineKeyboardButton("按钮3", callback_data='button3')

    keyboard = [[button1], [button2], [button3]]
    reply_markup = InlineKeyboardMarkup(keyboard)

    update.message.reply_text('请点击以下按钮：', reply_markup=reply_markup)

def button_click(update, context):
    query = update.callback_query
    query.answer()
    query.edit_message_text(text=f"你点击了按钮：{query.data}")

def main():
    updater = Updater('YOUR_TOKEN', use_context=True)
    dp = updater.dispatcher

    dp.add_handler(CommandHandler('start', start))
    dp.add_handler(CallbackQueryHandler(button_click))

    updater.start_polling()
    updater.idle()

if __name__ == '__main__':
    main()
