Playwright

Playwright module provides a method to launch a browser instance. The following is a typical example of using Playwright to drive automation:

Sync

from playwright.sync_api import sync_playwright, Playwright

def run(playwright: Playwright):
    chromium = playwright.chromium # or "firefox" or "webkit".
    browser = chromium.launch()
    page = browser.new_page()
    page.goto("http://example.com")
    # other actions...
    browser.close()

with sync_playwright() as playwright:
    run(playwright)

Async

import asyncio
from playwright.async_api import async_playwright, Playwright

async def run(playwright: Playwright):
    chromium = playwright.chromium # or "firefox" or "webkit".
    browser = await chromium.launch()
    page = await browser.new_page()
    await page.goto("http://example.com")
    # other actions...
    await browser.close()

async def main():
    async with async_playwright() as playwright:
        await run(playwright)
asyncio.run(main())
