How to remove u'' from python script result?

I'm trying to write parsing script using python/scrapy. How can I remove [] and u' from strings in result file?

Now I have text like this:

from scrapy.spider import BaseSpider
from scrapy.selector import HtmlXPathSelector
from scrapy.utils.markup import remove_tags
from googleparser.items import GoogleparserItem
import sys

class GoogleparserSpider(BaseSpider):
    name = "google.com"
    allowed_domains = ["google.com"]
    start_urls = [
        "http://www.google.com/search?q=this+is+first+test&num=20&hl=uk&start=0",
    "http://www.google.com/search?q=this+is+second+test&num=20&hl=uk&start=0"
    ]

    def parse(self, response):
       print "===START======================================================="
       hxs = HtmlXPathSelector(response)
       qqq = hxs.select('/html/head/title/text()').extract()
       print qqq
       print "---DATA--------------------------------------------------------"

       sites = hxs.select('/html/body/div[5]/div[3]/div/div/div/ol/li/h3')
       i = 1
       items = []
       for site in sites:
           try:
           item = GoogleparserItem()
           title1 = site.select('a').extract()
           title2=str(title1)
           title=remove_tags(title2)
           link=site.select('a/@href').extract()
               item['num'] = i  
           item['title'] = title
               item['link'] = link
               i= i+1
               items.append(item)
           except: 
               print 'EXCEPTION'
       return items
       print "===END========================================================="

SPIDER = GoogleparserSpider()

and I have result like this after running 

python scrapy-ctl.py crawl google.com

The u infront of the code, purely means it's a unicode string. See the reference here. http://docs.python.org/tutorial/introduction.html#unicode-strings. The fix would be to convert your content to a string using the str() method.

more prettier - print qqq.pop()

It looks like the result from extract is a list. Try:

print ', '.join(qqq)

Replace print qqq with print qqq[0]. You get that result because qqq is a list.

Same problem with your text file. You have a list with one element that you're writing instead of the element within the list.
