Question

well here is my project/spider , works fine....

    # -*- coding: utf-8 -*-
import scrapy
import time

class SccbotakiSpider(scrapy.Spider):
    name = 'SccBotaki'
    start_urls = ['url']
    time.sleep(1)

    def parse(self, response):
        daten = response.css('#daten').extract()
        cartext = response.css('div.car_header > b::text').extract()
        spacerimg = response.css('div.rechts > img::attr(src)').extract()
        inhalt = response.css('div.inhalt')
        prodname = inhalt.css('div.prod-name::text').extract()
        artnr = inhalt.css('div.art-nr > span::text').extract()
        avaible = inhalt.css('div.ampel > img::attr(src)').extract()
        price = inhalt.css('div.preis::text').extract()


        for item in zip(prodname,artnr,avaible,price):
            scraped_info = {
            'prodname' : item[0] ,
            'artnr' : item[1] ,
            'avaible' : item[2] ,
            'price' : item[3] ,
        }
            yield scraped_info

check out the url inside of image because i cannot use tiny url inside this post URL Image
but i wanted to scrape daten,cartext,spacerimg aswell im gonna get different/bad results btw in settings.py i did like that to export into csv file:

    #Export as CSV Feed
    FEED_FORMAT = "csv"
    FEED_URI = "UltraRacing.csv"

so, my question is why i cannot scrape like my image when im adding "daten,cartext,spacerimg"? if i did scrape all of them together im gonna get in csv just 1 row with all of the informations in 1 cell and if ill remove the "daten,cartext,spacerimg from the loop", ill get the perfect results....

hope this make sense...

Answer 1

你试图zip不同大小的列表： prodname ， artnr ， avaible ， price有41元，但daten和cartext只有1元和spacerimg是9个元素。
