如何使用pyppeteer打开新标签页中的url？

import asyncio
from pyppeteer import launch

loop = asyncio.get_event_loop()

async def open_new_tab():
    browser = await launch()
    page = await browser.newPage()
    await page.goto('http://www.example.com')

loop.run_until_complete(open_new_tab())

import asyncio
from pyppeteer import launch

async def open_new_tab():
    browser = await launch()
    page = await browser.newPage()
    await page.goto('http://www.example.com')

loop = asyncio.get_event_loop()
loop.run_until_complete(open_new_tab())
