Iterating articles on news source produces duplicates, if subdomain omitted.

I was testing news sources, and found that this article was emitted twice, despite the fact that newspaper should be memoizing. The problem seems to be that memoization uses the straight url and doesn't consider that the second source is missing the www subdomain.

import newspaper

def dump_article(a):
    try:
        a.download()
        a.parse()
        print(a.title)
        print(a.authors)
        # print (a.text)
        return True
    except :
        return False

MAX_PULL=10

for source in newspaper.popular_urls():
    print(source)
    pull=0
    s=newspaper.build(source,lang='en')
    for a in s.articles:
        print(a.url)
        if dump_article(a):
            pull+=1
        if pull>= MAX_PULL:
            break
