write a Python program to prompt for a URL, read the XML data from that URL using urllib and then parse and extract the comment counts from the XML data, compute the sum of the numbers in the file.

Extracting Data from XML.py

#Data file url:  http://py4e-data.dr-chuck.net/comments_1070214.xml
#VERSION 1:
import urllib.request
import xml.etree.ElementTree as ET
import ssl

# Ignore SSL certificate errors
ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE

url = input("Enter location: ")
response = urllib.request.urlopen(url)
print('Retrieving: ', url)
tree = ET.fromstring(response.read())
total = sum([int(count.text) for count in tree.findall('comments/comment/count')])
print("Sum: ", total)

#VERSION 2- My best
import urllib.request, urllib.parse, urllib.error
import xml.etree.ElementTree as ET
import ssl

ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE

while True:
    sum = 0
    address = input('Enter location: ')
    if len(address) < 1: break

    print('Retrieving', address)
    uh = urllib.request.urlopen(address, context=ctx)
    data = uh.read()
    print('Retrieved', len(data), 'characters')
    tree = ET.fromstring(data)
    counts = tree.findall('.//count')
    for i in counts :
        count = int(i.text)
        sum+= count
    print('count:',len(counts))
    print('sum:',sum)
