python - How to use scrapy request class -

Some may help me in requesting access to the scripts request class

I Have tried but it does not work: import scrapy.selector from HtmlXPathSelector from scrapy.http.request import request url = 'http://www.fetise.com' a = request (Url) hxs = HtmlXPathSelector (a)

error is:

  traceback (most recent call final): file "sa.py", line 83, & lt; Module & gt; In the Hxs = HtmlXPathSelector (A) file "/usr/local/lib/python2.7/dist-packages/scrapy/selector/lxmlsel.py"line-31, __init__ _root = LxmlDocument (response, self._parser) file" / Usr / local / lib / python2.7 / dist-packages / scrapy / selector / lxmldocument.py ", / usr / local / lib / python2 in line 27, __new__ cache [parser] = _factory (response, parser) file 7 / dist-packages / scrapy / selector / lxmldocument.py ", line 13, in _factor body = response.in_ass_oneOnod ().

HtmlXPathSelector Pprint import pprint url = 'http://www.fetise.com' .read () hxs = HtmlXPathSelector (text = data) from data = urllib.urlopen (url) lista = hxs.select ('// ul [@ Class = "categoryMenu"] / li / ul / li / a / @ href '). Remove () ACB = ["http://www.fetise.com/" + "If http://www.fetise.com/" in the list for Else i] + [u "http: // Www.fetise.com/sale "] pprint (acb)
