parsing - Python: How to turn two for-statements into one? -


i'm trying parse web table , export data csv file.

i'm ignorant forming 2 xpaths followed single for-statement (or maybe 2 correct?).

current spider:

class myspider(basespider):     symbols = ["scmp"]     name =  "dozen"     allowed_domains = ["yahoo.com"]          start_urls = ["http://finance.yahoo.com/q/is?s=scmp&annual"]      def parse(self, response):         hxs = htmlxpathselector(response)         revenue = response.xpath('//td[@align="right"]/strong/text()')         date = response.xpath('//tr[@class="yfnc_modtitle1"]/th/text()')         items = []         rev in revenue:             item = dozenitem()             item["revenue"] = rev.re('\d*,\d*')             items.append(item)         return items[:3]         days = []         day in dates:             item = dozenitem()             item["date"] = day.re('\d*')             days.append(item)         return items[:3]

i know needs work, i'm not sure direction go...?

this output:

export

as visible, can't dates fill in.

here html i'm parsing dates from:

<tr class="yfnc_modtitle1" style="border-top:none;">  <th scope="col" style="border-top:2px solid #000;text-align:right; font-weight:bold">dec 31, 2014</th>  <th scope="col" style="border-top:2px solid #000;text-align:right; font-weight:bold">dec 31, 2013</th> <th scope="col" style="border-top:2px solid #000;text-align:right; font-weight:bold">dec 31, 2012</th> </tr> <tr> <td colspan="2"> 

for rev, day in zip(revenue, dates):     pass # code here
