Extracting Data from XML: The program will 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.

from urllib import request
import xml.etree.ElementTree as ET

url = 'http://python-data.dr-chuck.net/comments_24966.xml'
print ("Retrieving", url)
html = request.urlopen(url)
data = html.read()
print("Retrieved",len(data),"characters")

tree = ET.fromstring(data)
results = tree.findall('comments/comment')
icount=len(results)
isum=0

for result in results:
    isum += float(result.find('count').text)
print(icount)
print(isum)

That works! Thanks!

Thanks

Edit: it was the file name. changed it from xml.py to week5.py and worked out. thanks!

why I keep having this error ?

i am getting error :-
