windows_before = driver.window_handles
driver.find_element_by_css_selector("[href='http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2']").click()
windows_after = driver.window_handles
new_window =
driver.switch_to_window(new_window)
driver.close()
driver.switch_to_window(windows_before)
Please can someone tell me how can I get the id of new window.
I have windows_before = 'CDwindow-8b18d716-650e-4793-ac69-10532978004c'
than I have list with id of old and new windows ['CDwindow-8b18d716-650e-4793-ac69-10532978004c', 'CDwindow-1b199b20-c50e-4301-bbea-9f0f8faa2902']
How can I get the element from my list that not match with windows_before?
Thank you
