它应该是visibility_of_all_elements_located()，它返回元素列表。

about_this_item_divs = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//div[@id='featurebullets_feature_div']//ul//li//span")))

这将仅返回Web元素而不是Web元素列表。

about_this_item_divs = WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//div[@id='featurebullets_feature_div']//ul//li//span")))

更新：

您似乎需要滚动页面才能看到元素。尝试使用presence_of_all_elements_located()

about_this_item_divs = WebDriverWait(driver, 20).until(EC.presence_of_all_elements_located((By.XPATH, "//div[@id='featurebullets_feature_div']//ul//li//span")))

输出：
