使用python-anydrop进行Selenium web抓取

我想知道如何通过所有的下拉列表,得到价格和变化名称。我可以通过name属性来实现这一点,但是不同的产品页面有不同的属性,所以这不是最佳实践。我使用select by element id完成了这段代码,但收到了下面的错误。我也在试图找出如何复制到csv的这一点,但似乎没有工作。

import csv
browser = webdriver.Chrome(executable_path='C:\Users\userman\PycharmProjects\seleniumTest\drivers\chromedriver.exe')
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import Select
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
from selenium.webdriver.support.select import Select

url = "https://www.ebay.co.uk/itm/Pashmina-Scarf-100-Viscose-Plain-Wrap-Shawl-Stole-Scarf-Many-Colours-Available/252342060680"

browser.get(url)
optionones = len(browser.find_elements_by_xpath("//select[@id='msku-sel-1']/option"))
for colNum in range(optionones):
    #select color
    optiononeEle = browser.find_element_by_xpath("(//select[id='msku-sel-1']/option)[" + str(colNum+1) + "]")
    optionone = optiononeEle.text
    optiononeEle.click()

    # get the sizes
    sizes = len(browser.find_elements_by_xpath("//select[id='msku-sel-2']/option"))
    for sizeNum in range(sizes):
        # select optionone
        optiontwoEle = browser.find_element_by_xpath("(//select[id='msku-sel-2']/option)[" + str(sizeNum + 1) + "]")
        size = optiontwoEle.text
        optiontwoEle.click()
        price = browser.find_element_by_xpath("//span[@id='prcIsum']").text
        print ("optionone:" + optionone)
        print( "optiontwoEle:" + optiontwoEle)
        print("Price: "+ price)
        print ("----------------------------------------")
