Scrapy - crawled (200) and referer : none

I'm trying to learn how to use scrapy and python but I'm not an expert at all... very far from here. I always have an empty file after crawling this page : product of c-discount and I don't understand why...

Here is my code :

import scrapy

from cdiscount_test.items import CdiscountTestItem

f = open('items.csv', 'w').close()

class CdiscountsellersspiderSpider(scrapy.Spider):
    name = 'CDiscountSellersSpider'
    allowed_domains = ['cdiscount.com']
    start_urls = ['http://www.cdiscount.com/mpv-8732-SATENCO.html']

    def parse(self, response):
        items = CdiscountTestItem()
        name = response.xpath('//div[@class="shtName"]/div[@class="shtOver"]/h1[@itemprop="name"]/text()').extract()
        country = response.xpath('//div[@class="shtName"]/span[@class="shTopCExp"]/text()').extract()

        items['name_seller'] = ''.join(name).strip()
        items['country_seller'] = ''.join(country).strip()
        pass

And the result I get in the cmd windows :

2017-06-20 18:01:51 [scrapy.core.engine] INFO: Closing spider (finished)

Is there someone to help me please?

Thanks a lot!!!

The main problem here is that you don't pass the item from the parse method back to Scrapy engine. Your last command in parse is pass, so you just discard the item. Instead, you need to pass the item from spider to Scrapy engine for further processing using yield item.
