Parsing html page and working with checkbox (on a captcha)

[straannick]

Take a look at this post.
So it can work similar when a new window show most switch with browser.switch_to.frame(0).
Then can find element and click and throw in a time.sleep(3) to behave like human.
I have not tested i'm a not robot captcha yet,just some tough on what i would tried first.

Thank you.
About problem 2.
I suppose switch_to.frame(0) is not needed, because I selected (finded) other elements successfully. The main problem for me is how to find captcha checkbox and what should I find - "recaptcha-checkbox-checkmark" or other (see captcha.jpg)?
Here is different finds with errors:
v1. elem_capt = driver.find_element_by_id("recaptcha-checkbox-checkmark")
elem_capt.select()
selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":"[id="recaptcha-checkbox-checkmark"]"}

v2. elem_capt = driver.find_element_by_class_name("recaptcha-checkbox-checkmark")
elem_capt.select()
selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":".recaptcha-checkbox-checkmark"}

v3. elem_capt = driver.find_elements_by_css_selector("recaptcha-checkbox-checkmark")
elem_capt.select()
AttributeError: 'list' object has no attribute 'select'

v3 looks preferable, but how to choose what I need from this 'list' to 'select'?
Unfortunately "print(len(elem_capt))" prints '0'

So if I write
elem_capt = driver.find_elements_by_css_selector("recaptcha-checkbox-checkmark")[0]
I got IndexError: list index out of range

Additionally, I would like to note that problem 1 is still not resolved.
