Click on coordinates in Selenium Webdriver Python?

Question

Python

You need to click on the coordinates on the site using Selenium Webdriver Python.
I got this code:

driver = webdriver.Firefox()
driver.get("http://localhost/pythontest.com/")
actions = ActionChains(driver)
actions.move_by_offset(100, 100).click()

It works and nothing happens, even though the test site has a full-screen link. I'm not strong in English, I deal with the documentation with a translator.
Is it possible to find out the mouse coordinates, maybe I'm clicking in the wrong place?

Answer 1

it was necessary to add perform();
working version:

actions = ActionChains(driver)
actions.move_by_offset(100, 100).perform()
time.sleep(5)
actions.click().perform()
