#author: dfdeshom , http://www.bigbold.com/snippets/user/dfdeshom/14

#We are using python's delicious-py module

def get_popular_count(user="user"):
import delicious
notapi = delicious.DeliciousNOTAPI()

#Get user's posts
user_posts = notapi.get_posts_by_user(user)
data = '#tagID popularity\n'

#For each url, get how popular it is
for i in range(len(user_posts)):
data += str(i)+" "+str(len(notapi.get_posts_by_url(user_posts[i]["url"])))+'\n'
str1 = user + "-data" #file name
data_file = file(str1,'w')
data_file.write(data)
data_file.close()
The resulting file will look like this:
$ less jemisa-data
