Answer 1

To go into nested iframes and then click the button with text Continuar.

wait = WebDriverWait(driver, 10)
wait.until(ec.frame_to_be_available_and_switch_to_it((By.XPATH,"//frame[@name='reloj']" )))
wait.until(ec.frame_to_be_available_and_switch_to_it((By.XPATH,"//frame[@name='transicion']")))
wait.until(ec.frame_to_be_available_and_switch_to_it((By.XPATH,"//button[text()='Continuar']"))).click()

Import

from selenium.webdriver.support import expected_conditions as ec
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
