在selenium python中选择一个值（选项值和文本）

这里是python和selenium的新手；我有一个无法解决的问题，我读过很多关于选择、下拉、选项值等的文章。 我有html代码，只显示第一行，有几十行：

<select id="Site" name="Site" style="width:495px"><option selected="selected" value=""></option>
<option value="GroupId61534">FELICIANO  STA.CRUZ DE TENERIFE ES74048001 STA.CRUZ DE TENERIFE 38108     </option>
<option value="GroupId78984"> HELADOS  SAN VICENTE DEL RASP ES07683000 SAN VICENTE DEL RASP 03690     </option>
<option value="GroupId72067"> LEVANTE  RIBARROJA (VALENCIA) ES07898001 RIBARROJA (VALENCIA) 46190</option>

我不知道如何在整个列表中迭代，并仅使用ESnumber作为唯一的初始信息进行查找和选择 我已经读过很多其他的文章，也看到了一些想法，但是我无法让它工作

没有成功

all_options = element.find_elements_by_tag_name("option")
 


#SiteNumber got from a archive succesfully
SitesList = driver.find_element_by_xpath ('//*[contains(text(), %s)]' % 'SiteNumber')
SitesList.click
#List all the text of all lines, not click any and not found the proper SiteNumber ESXXXX


SitesList = driver.find_element_by_xpath ('//*[contains(text(), %s)]' % 'SiteNumber')
select = Select(SitesList)
select.select_by_visible_text('SiteNumber')

FULLXPATH "//html/body/div[4]/div[2]/div/div[1]/form/div/div[4]/div[11]/option[i])"
#i = line number

Need help!!
Any little help will be appreaciated!
Many thanks in advance
