How to remove a certain part of a string in scrapy for python

Question

I'm trying to get a clean output because When I scrape the website it gives, reviewed 7/20/2015 so I am trying to strip it so it only shows 7/20/2015. This is what I've been trying and when I test it by itself making a mock dict and populate it with values this code works but not in scrapy. I assume Field() is just dict = {value:[],value2:[]} so I dont know Why it does not work on Field()

Here's the code snippet

for j in range(len(item['date'])):
    item['date'][j][9:].strip()

我将使用选择器的内置re()方法：

response.xpath("//div[@id='test']/text()").re(r"\d{1,2}/\d{1,2}/\d{4}")
