Delicious CSV Import Script

delicious.py

#!/usr/bin/env python

import csv
import httplib2
import time

from urllib import urlencode

add_url = 'https://api.del.icio.us/v1/posts/add?%s'
ifile = ''
headers = {'User-Agent': 'Delicious CSV Import'}
bookmarks = csv.DictReader(open(ifile, 'r'))

for row in bookmarks:
    post_dict = {}
    post_dict['url'] = row['URL']
    post_dict['description'] = row['Title']
    post_dict['tags'] = row['Folder']
    post_dict['replace'] = 'no'
    print post_dict
    h = httplib2.Http()
    h.add_credentials(username, pass)
    params = urlencode(post_dict)
    resp, content = h.request(add_url % params, "GET", headers=headers)
    print resp
    print content
    #they ask us to pause for at least a second, give them 2 to be kosher.
    time.sleep(2)

How to use it, can you specify an example of command line ?
Thanks!

EDIT : I found. Import succeed.
