====Extracting Data from JSON: ==== The program will prompt for a URL, read the JSON data from that URL using urllib and then parse and extract the comment counts from the JSON data, compute the sum of the numbers in the file and provide the sum.

import urllib	#importing urllib
import json		#importing json

#requesting a json file url
url = raw_input("Enter the URL:")		
#load json file as list -info
info = json.loads(urllib.urlopen(url).read())

x = 0 
#loop through each item in list comments
for items in info['comments']:
#loop through the value of the key count in the list and add 
	x = x + int(items['count'])
print 'count: ',(x)

Here is a simplified code:

import urllib.request, urllib.parse, urllib.error
import json

url = "The URL"
info = json.loads(urllib.request.urlopen(url).read())

comm=info['comments']
counts_list = [int(items['count']) for items in comm]
print(sum(counts_list))
