%d（整数）など

複数ページ

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {“method”:”css selector”,”selector”:”span.race:nth-of-type(1)”}

for i in driver.find_elements_by_css_selector('span.race')

ではページ離れると駄目なので、ページ戻るごとに読み込ませる

len = len(elements)
for i in range(len):
elements = driver.find_elements_by_css_selector('span.race')
    elements[i].click()
