wait.until(EC.element_located_selection_state_to_be((By.ID, "peach"), True))

③ element_located_to_be_selected()

　期望元素处于选中状态

wait = WebDriverWait(driver,10)
wait.until(EC.element_located_to_be_selected((By.ID, "xxx")))
wait.until(EC.element_located_to_be_selected(driver.find_element_by_id("xxx")))

④ element_to_be_clickable()

　　判断元素是否可见并能被单击

wait = WebDriverWait(driver,10)
wait.until(EC.element_to_be_clickable(By.ID, "xxx"))
