Here's how to initialize playwright browser globally without context managers.
In your particular code, this will work like below:
from playwright.sync_api import Playwright, sync_playwright
locationList = [
'London Luton Airport',
'London Hilton',
'London City',
'London Wembley',
'London Battersea',
'London Shepherds Bush'
]
playwright = sync_playwright().start() # <-- Use this to initialize playwright globally
chromium = playwright.chromium
browser = chromium.launch(channel="chrome", headless=False)
page = browser.new_page()
page.set_viewport_size({"width": 1920, "height": 1080})
page.goto("https://www.sixt.co.uk/")
page.locator("[data-testid=\"uc-accept-all-button\"]").click()
page.locator("[placeholder=\"Find a location\"]").click()
page.locator("[placeholder=\"Find a location\"]").fill("luton")
page.locator("text=London Luton Airport (GB)").click()
page.locator("button:has-text(\"Show offers\")").click()
def run(playwright: Playwright):
page.locator("[placeholder=\"Find a location\"]").click()
page.locator("[placeholder=\"Find a location\"]").fill(loc)
page.locator('//div[text()="' + loc + '"]').click()
carnames = page.locator("//h2[@class='vehicle-item__title']")
#Get all carnames in a list
carnamelist = [cars.text for cars in carnames]
for loc in locationList:
run(playwright)
playwright.stop() # --> Cleanup resources properly when done
However, you can also initialize page
and browser
from inside the context manager you create in the original question, and it will work as expected.

Websites and web apps are growing in number day by day, and so are the expectations of people for a pleasant web experience. Even though the World Wide Web (WWW) was invented only in 1989 (32 years back), this technology has revolutionized the world we know back then. The best part is that it has made life easier for us. You no longer have to stand in long queues to pay your bills. You can get that done within a few minutes by visiting their website, web app, or mobile app.
We were eager to listen to Manoj Kumar, VP Developer Relations, LambdaTest, speak on the importance of Selenium 4.0 and how bright the future is. This was the agenda of the speech:
To decide what automation technology to use, we brought together Joe Colantonio, Founder of TestGuild, Sneha. V, Director of Quality Engineering, Everfi, and Carlos Kidman, Director of Engineering, Stealth Startup. The panel discussion was hosted by Mudit Singh, Marketing head at LambdaTest. Mudit decided to take a step backwards and let the panel discussion happen.
With the rapidly evolving technology due to its ever-increasing demand in today’s world, Digital Security has become a major concern for the Software Industry. There are various ways through which Digital Security can be achieved, Captcha being one of them.Captcha is easy for humans to solve but hard for “bots” and other malicious software to figure out. However, Captcha has always been tricky for the testers to automate, as many of them don’t know how to handle captcha in Selenium or using any other test automation framework.
