Python 从csv中提取数据的问题

这是一个尝试从csv文件（第3列中包含提取公司名称）检查谷歌电子邮件的代码。 第一列包含我想在csv中提取为“SIRET”的信息。 我怎么做

如果我在读取csv时在start_url中提取它，我的url将是错误的。如果我使用它来解析，我不会：解析与数据相关的好数据，我可能会有错误，因为访问一个文件2次

如何使第一次读取的信息进入解析函数中的SIRET

我为此挣扎了几个小时：（

最好的，我们可以使用它

class QuotesSpider(scrapy.Spider):
    name = "googlemailverif"

    with open('input.csv', "r") as csvfile:
        datareader = csv.reader(csvfile)

        start_urls=['https://www.google.fr/search?q=email'+str(row[2]) for row in datareader]



    # starting parsing
    def parse(self, response):
        yield {
                'url': response.url,
                'nom': "nom",
                'emails': re.findall(r"[a-zA-Z0-9_\.+-]+@[a-zA-Z0-9_\.+-]+\.[a-zA-Z]{2,6}",''.join(response.xpath("//body//text()").extract()).strip()),
                'SIRET':"SIRET",
                    }

现在您有了一个包含SIRET值的列表和另一个包含url的列表

sirets, start_urls = zip(*[(row[0], 'https://www.google.fr/search?q=email'+str(row[2])) for row in datareader])

这是csv的摘录

每次我都有一个“SIRET”作为sirets值，但另一个var每次都会递增和更改

非常感谢+++

查看scrapy的文档，特别是method@roganjosh如果您查看原始问题，您将看到它已经是一个类，但格式不正确。我所做的只是Ctrl-kThanks，这非常令人鼓舞！尽管如此，self.sirets[0]或者self.siret总是显示第一行，在第1行之后什么也不显示..我不知道如何增加变量sirets您能从

数据读取器

发布几行吗？没有数据就很难调试我想我理解了一些东西。当给出变量行[0]对于sirets，它不会进入scrapy进入的过程。因此，var没有正确递增。实际上，var应该与中间件中的url以及要在摘录中排序的管道一起。您知道如何做到这一点吗/
