Extracting the Address tag from multiple HTML files using BeautifulSoup

[buran]

I didn't look at your code into depth. Now I see see it's a bit weird. You iterate over bunch of files, to read first title in separate list, then again to read address(es).

There is no need to use find_all for title - it is expected to have only one tag title, right? Just use soup.find()
Then, is it one address or multiple in each file?
You write to a file after you have exited the second loop. But using list-comprehension will give you only the data from last file not all files (i.e. like when you append to a single list) - this is something I overlooked.
Finally if write 2 lists, but I don't think it will give you what you expect anyway.

import csv
path = "C:\\Users\\mzoljan\\Downloads\\lksd\\"
 
for infile in glob.glob(os.path.join(path, "*.html")):
    with open(infile, "r") as f, open('output2.csv', 'а') as myfile:
        writer = csv.writer(myfile)
        soup = BeautifulSoup(f.read(), 'lxml')
        title = soup.find("title")
        if title:
           title = soup.title.string
        else:
            title = '' # just in case there is no title tag
        address = soup.find_all("address", class_={"styles_address__zrPvy"}) # do you really need find_all?
        for item in address:
            writer.writerow([title, item.string])

Note, the code is not tested as I don't have your html files.
