更新：

谢谢NitishKshirsagar 现在正在工作：

drop_down = driver.find_element_by_css_selector('#ctl00_PlaceHolderMain_oDistributionUC_trClass .divDistributionSearchData')

ActionChains(driver).move_to_element(drop_down).perform()
drop_down.click()
drop_down = driver.switch_to.active_element

element = driver.find_element_by_css_selector("#ctl00_PlaceHolderMain_oDistributionUC_trClass .divDistributionSearchData select")
all_options = element.find_elements_by_tag_name("option")
for option in all_options:
    print(option.text)

由于下拉列表不是Select类型，因此不能在此下拉列表上使用Select方法。您需要使用xpath单击元素。 你可以这样做：

em = driver.find_elements_by_xpath("//span[@class='select2-selection select2-selection single']//span[@id='select2-ctl00_PlaceHolderMain_oDistributionUC_ddlClass-container']")
