Syntax issue : response.css(.title::text).extract() is returning a null set



So, I have been struggling with this problem, I have created a virtual environment on anaconda having python 2.7, I installed scrapy 1.4.0 , and am trying to run the code request.css(.title::text).extract(), on this virtual environment. If i do response.css(title::text).extract() i am getting the output : [u’Game of Thrones’, u’Hot’, u’Hot’]
Kindly help with this.
