Write to a csv file scrapy

Question

I want to write to csv file in scrapy

 for rss in rsslinks:
  item = AppleItem()
  item[\'reference_link\'] = response.url
  base_url = get_base_url(response         


        

Answer 1

You need to

1. Write your header row; then
2. Write the entry rows for each object.

You could approach it like:

fields = ["reference_link", "rss_link"] # define fields to use
with open(filename,'a+') as f: # handle the source file
    f.write("{}\n".format('\t'.join(str(field) 
                              for field in fields))) # write header 
    for item in items:
        f.write("{}\n".format('\t'.join(str(item[field]) 
                              for field in fields))) # write items

Note that "{}\n".format(s) gives the same result as "%s\n" % s.
