python scrapy不从字符串中删除\ n

Question

我有大约200个值，我已经完成了删除新行字符的所有内容＆＃39; \ n＆＃39; 尝试了所有这些

prodname = str(row['productname'])
prodname = ''.join(prodname.split('[u\'\n', 1))
prodname = ''.join(prodname.split('[u\'', 1))
prodname = ''.join(prodname.split('\']', 1))
prodname = ''.join(prodname.split('\n', 1))
prodname = prodname.replace('\n', '')

我的价值观仍然像这样......任何想法为什么???

这是蜘蛛代码

class ShopBot(Spider):
    name = "shopbot"
    allowed_domains = ["shopbot.com.au"]
    start_urls = [
        "http://www.shopbot.com.au/apple-iphone-unlocked/price/australia/13721",
        "http://www.shopbot.com.au/m/?m=apple-iphone-unlocked&page=2"
        "http://www.shopbot.com.au/m/?m=apple-iphone-unlocked&page=3",
        "http://www.shopbot.com.au/laptops/laptop,-tablet-pda/australia/115",
        "http://www.shopbot.com.au/laptops/laptop,-tablet-pda/australia/115/order/0/page/2",
        "http://www.shopbot.com.au/laptops/laptop,-tablet-pda/australia/115/order/0/page/3",
        "http://www.shopbot.com.au/laptops/laptop,-tablet-pda/australia/115/order/0/page/4",
        "http://www.shopbot.com.au/laptops/laptop,-tablet-pda/australia/115/order/0/page/5"
    ]

    def parse(self, response):
        sel = Selector(response)
        prodsel = sel.xpath('//div[@id="content"]/div[@class="left"]/ul[@id="results"]/li[@class="result"]/ol')

        #productnames = sel.xpath('//ul[@class="navigation"]/li/dl/dt[@class="title"]/a/text()').extract()
        #price = sel.xpath('//ul[@class="navigation"]/li/dl/dd[@class="price"]/span[@class="main"]/text()').extract()
        items = []
        for site in prodsel:
            item = ArgosItems()
            item['productname'] = site.xpath('li[@class="details"]/span[@rel="external"]/text()').extract()
            item['price'] = site.xpath('li[@class="action"]/div[@class="price"]/span/text()').extract()
            item['siteid'] = 2
            items.append(item)
        return items

这就是im处理它以将其保存在db

中的地方

def spider_closed(spider):
    config = {
          'user': 'root',
          'password': 'root',
          'host': '127.0.0.1',
          'database': 'pricewatch',
          'raise_on_warnings': True,
          'buffered': True,
        }
    cnx = mysql.connector.connect(**config)
    cursor = cnx.cursor()
    today = datetime.now()
    print today

    count = 0

    for row in results:

        prodname = str(row['productname'])
        prodname = ''.join(prodname.split('[u\'\n', 1))
        prodname = ''.join(prodname.split('[u\'', 1))
        prodname = ''.join(prodname.split('\']', 1))
        prodname = ''.join(prodname.split('\n', 1))
        prodname = prodname.replace('\n', '')

        price = str(row['price'])
        price = ''.join(price.split('$', 1))
        price = ''.join(price.split('[u\'', 1))
        price = ''.join(price.split('\']', 1))
        price = ''.join(price.split('\n', 1))
        price = price.replace('\n','')

        siteid = row['siteid']

注意：我从python脚本运行scrapy，名为pricewatch.py​​
