Web Scraper sectioned in different files

I have been working on a Python scraper for a while.
I want to save the information I get in different files. URLs must be in one file and captions must be in another file.

While working with URLs there is no issue, but when I try to scrape the names of the blog I’m searching for, I get this result:

w

I have identified the problem and I think it is related to the ‘\n’, but I have not been able to find a solution.

This is my code:

from bs4 import BeautifulSoup

search_term = "landscape/recent"
posts_scrape = requests.get(f"https://www.tumblr.com/search/{search_term}")
soup = BeautifulSoup(posts_scrape.text, "html.parser")

articles = soup.find_all("article", class_="FtjPK")

data = {}
for article in articles:
    try:
        source = article.find("div", class_="vGkyT").text
        for imgvar in article.find_all("img", alt="Image"):
            data.setdefault(source, []).extend(
                [
                    i.replace("500w", "").strip()
                    for i in imgvar["srcset"].split(",")
                    if "500w" in i
                ]
            )
    except AttributeError:
        continue


archivo = open ("Sites.txt", "w")
for source, image_urls in data.items():
    for url in image_urls:
        archivo.write(url + '\n')
archivo.close()


archivo = open ("Source.txt", "w")
for source, image_urls in data.items():
    for sources in source:
        archivo.write(sources + '\n')
archivo.close()

>Solution :

Change the last loop to:

archivo = open("Source.txt", "w")
for source in data:
    archivo.write(source + "\n")
archivo.close()

Then the content of Source.txt will be:

harshvardhan25
mikeahrens
amazinglybeautifulphotography
landscaperrosebay
danielapelli
sahrish-acrylic-painting
sweetd3lights
pensamentsisomnis
pics-bae
oneshotolive
scattopermestesso
huariqueje

Or using with:

with open("Source.txt", "w") as archivo:
    archivo.write("\n".join(data))
