This method as I know currently works with Edge only – Burkle

It doesn't look like you can screenshot a particular element with selenium alone. See here, for example: How to take screenshot of element using python3 and selenium.

There are workarounds such as this: How to take partial screenshot with Selenium WebDriver in python?.

You can also take a screenshot of the page and crop it. In that case, these work:

browser.get_screenshot_as_file('/example/file/path.png')

or

browser.save_screenshot('/example/file/path.png')

What about selenium-python.readthedocs.io/… ? – Question

Has that worked for you? I've tried element.screenshot(file) a few times and it has never worked. That's what the original poster was trying also. – Brody

It seems that it has not been implemented yet. Take a look at this. – Question
