A: Try to use that code:
import time

from selenium import webdriver

driver = webdriver.Chrome()
driver.get("https://www.netacad.com/portal/saml_login")
time.sleep(3)
el = driver.find_element_by_xpath("//input[@class='input--dirty input--valid inputDom']")
el.send_keys("you email")
time.sleep(3)
driver.quit()
