option.add_experimental_option("detach", True)

This line of code is used to add an experimental option to a Selenium WebDriver object. Specifically, it adds the "detach" option with a value of "True".

The "detach" option allows the WebDriver to detach itself from the browser process after it is launched. This means that the WebDriver can continue to run even if the browser window is closed, which can be useful for certain testing scenarios.

However, it's important to note that this is an experimental option, which means that it may not be fully stable or supported in all cases. It's always a good idea to thoroughly test your code and make sure that the "detach" option is working as expected before relying on it for your testing needs.
