driver1.find_element_by_xpath(...).click()

if it wasn't clear, i want to click this button ( in the circle )

Answer 1

The xpath is //*[@class="recaptcha-checkbox-checkmark"]

The checkbox is inside iframe first you need to switch to the frame then you can find element and click.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import TimeoutException

driver1 = webdriver.Firefox()
driver1.get("https://www.google.com/recaptcha/api2/demo")
driver1.switch_to.frame(driver.find_element_by_css_selector('iframe'))
driver1.find_element_by_xpath('//*[@class="recaptcha-checkbox-checkmark"]').click()

I have tried with java and it is able to click on the checkbox, the java code is given below.

driver=new FirefoxDriver();
driver.get("https://www.google.com/recaptcha/api2/demo");
driver.switchTo().frame(0);
new WebDriverWait(driver, 120).until(ExpectedConditions.visibilityOf(driver.findElement(By.className("recaptcha-checkbox-checkmark")))).click();

Answer 2

Switching to iFrames catches a lot of people out, but if you have content that is loaded from a different domain (in this case the Captcha) then you need to switch to that with

driver.switchTo().frame(<integer of frame or id>);

Then you will be be able to interact the selector of your choice.
