langdetect_test.py

#!/usr/bin/env python

import csv
from xml.etree import ElementTree
from langdetect import detect_langs
from requests_html import HTMLSession

http = HTMLSession()

def langs(url):
    resp = http.get(url)
    main = resp.html.find('section.main', first=True)
    return {l.lang: l.prob for l in detect_langs(main.text)}

def urls():
    doc = ElementTree.fromstring(http.get('https://usbeketrica.com/sitemap.xml').text)
    for url in doc.findall('.//{http://www.google.com/schemas/sitemap/0.84}loc'):
        if url.text.startswith('https://usbeketrica.com/article/'):
            yield url.text


output = csv.writer(open('langs.csv', 'w'))
output.writerow(['url', 'fr', 'en'])

for url in urls():
    results = langs(url)
    print(url, results)
    output.writerow([url, results.get('fr', 0), results.get('en', 0)])

it is working for me
