Installation
Use pip to install Playwright in your Python project. See system requirements.
$ pip install playwright
$ playwright install
These commands download the Playwright package and install browser binaries for Chromium, Firefox and WebKit. To modify this behavior see installation parameters.
Usage
Once installed, you can import
Playwright in a Python script, and launch any of the 3 browsers (chromium
, firefox
and webkit
).
from playwright.sync_api import sync_playwright
with sync_playwright() as p:
browser = p.chromium.launch()
page = browser.new_page()
page.goto("http://playwright.dev")
print(page.title())
browser.close()
Playwright supports two variations of the API: synchronous and asynchronous. If your modern project uses asyncio, you should use async API:
import asyncio
from playwright.async_api import async_playwright
async def main():
async with async_playwright() as p:
browser = await p.chromium.launch()
page = await browser.new_page()
await page.goto("http://playwright.dev")
print(await page.title())
await browser.close()
asyncio.run(main())
First script
In our first script, we will navigate to whatsmyuseragent.org
and take a screenshot in WebKit.
from playwright.sync_api import sync_playwright
with sync_playwright() as p:
browser = p.webkit.launch()
page = browser.new_page()
page.goto("http://whatsmyuseragent.org/")
page.screenshot(path="example.png")
browser.close()
By default, Playwright runs the browsers in headless mode. To see the browser UI, pass the headless=False
flag while launching the browser. You can also use [option: slowMo
] to slow down execution. Learn more in the debugging tools section.
firefox.launch(headless=False, slow_mo=50)
Record scripts
Command Line Interface CLI can be used to record user interactions and generate Python code.
$ playwright codegen wikipedia.org
System requirements
Playwright requires Python 3.7 or above. The browser binaries for Chromium, Firefox and WebKit work across the 3 platforms (Windows, macOS, Linux):
Windows
Works with Windows and Windows Subsystem for Linux (WSL).
macOS
Requires 10.14 (Mojave) or above.
Linux
Depending on your Linux distribution, you might need to install additional dependencies to run the browsers.
:::note Only Ubuntu 18.04 and Ubuntu 20.04 are officially supported. :::
See also in the Command Line Interface which has a command to install all necessary dependencies automatically for Ubuntu LTS releases.
