I'm trying to get wikipedia backlinks of more than 200 pages. To do this, I:

• look for URLs in italian, if it doesn't work I look for them in English
• put them in a list
• iterate over this list to get the number of languages they are available in on Wikipedia (with bs4)
• I append these languages in a list
• I iterate over both languages and urls to get page titles and backlinks to put in a dictinonary with key the language and value the number of backlinks available in that language

But I get the error "query". I don't know why

opere = df.label #works
listaurl = []
for x in opere:
    try:
        wiki_wiki = wikipediaapi.Wikipedia('it')
        p = wiki_wiki.page(x).fullurl
        listaurl.append(p)
        print(p)
    except:
        wiki_wiki = wikipediaapi.Wikipedia('en')
        p = wiki_wiki.page(x).fullurl
        listaurl.append(p)
        print(p)


lista = []
for url in listaurl:
    soup = BeautifulSoup(urllib.request.urlopen(url))
    links = [(el.get('lang'), el.get('href')) for el in soup.select('li.interlanguage-link > a')]

    for language, link in links:
        lista.append(language)
testo = soup.title.text.replace(" ", "")
import wikipediaapi
lista2 = []
regex = r"(?<=/wiki/).*$"
dik = {}
for lang in lista:
    wikis = wikipediaapi.Wikipedia(lang)
    for apage in listaurl:
        wikipage = apage.split('/wiki/')[1]
        page_py = wikis.page(wikipage)
        print(page_py)
        titles = page_py.title
        print(titles)
        back = page_py.backlinks
        dik[lang] = len(back)
