How to take screenshot of element using python3 and selenium

I want to take screenshot of the element. I tried with below mentioned code:


but got error:

File "C:\Python34\lib\site-packages\selenium-2.47.1-y3.4.egg\selenium\webdriver\remote\", line 448, in _execute   return self._parent.execute(command, params)
File "C:\Python34\lib\site-packages\selenium-2.47.1-y3.4.egg\selenium\webdriver\remote\", line 196, in execute self.error_handler.check_response(response)
File "C:\Python34\lib\site-packages\selenium-2.47.1-py3.4.egg\selenium\webdriver\remote\", line 102, in check_responsevalue = json.loads(value_json)
File "C:\Python34\lib\json\", line 318, in loads   return _default_decoder.decode(s)
File "C:\Python34\lib\json\", line 343, in decode   obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "C:\Python34\lib\json\", line 361, in raw_decode raise ValueError(errmsg("Expecting value", s, err.value)) from None ValueError: Expecting value: line 1 column 1 (char 0)


A couple of problems:

  1. find_elements_by_xpath returns a list, and you can't request a screenshot on a list. Did you mean find_element_by_xpath?
  2. In any case, with the exception of Microsoft Edge, no WebDriver actually implements element-based screenshots. You have to generate a full-window screenshot and crop it.

See my earlier answer on this topic for more background and workarounds.

With Firefox you can:

driver = webdriver.Firefox()
qr = driver.find_element_by_css_selector('.css_class')

You can use class, id or tags in find_element_by_css_selector.
