[Python] How do you open multiple pages asynchronously with Playwright Python?

I want to open multiple urls at once using Playwright for Python. But I am struggling to figure out how. This is from the async documentation:

async def main():
async with async_playwright() as p:
for browser_type in [p.chromium, p.firefox, p.webkit]:
browser = await browser_type.launch()
page = await browser.newPage()
await page.goto("https://scrapingant.com/")
await page.screenshot(path=f"scrapingant-{browser_type.name}.png")
await browser.close()

asyncio.get_event_loop().run_until_complete(main())


This opens each browser_type sequentially. How would I go about it if I wanted to do it in parallel? And how would I go about it if I wanted to do something similar with a list of urls?

I tried doing this:

urls = [
"https://scrapethissite.com/pages/ajax-javascript/#2015",
"https://scrapethissite.com/pages/ajax-javascript/#2014",
]
async def main(url):
async with async_playwright() as p:
browser = await p.chromium.launch(headless=False)
page = await browser.newPage()
await page.goto(url)
await browser.close()

async def go_to_url():
tasks = [main(url) for url in urls]
await asyncio.wait(tasks)

go_to_url()


But that gave me the following error:

92: RuntimeWarning: coroutine 'go_to_url' was never awaited
go_to_url()
RuntimeWarning: Enable tracemalloc to get the object allocation traceback
