Web scraper not populating .txt with scraped data

[BlackHeart]

Thank you! That helped a lot, and that was such a great tip. I actually got it to work here is my code:

import requests
from bs4 import BeautifulSoup
from urllib.parse import urljoin

# Scrape the links to each monthly results page
url = "http://www.calotteryx.com/Fantasy-5/drawing-results-calendar.htm"
response = requests.get(url)
content = response.content
soup = BeautifulSoup(content, 'html.parser')
links = []
Base_url = 'http://www.calotteryx.com'
for link in soup.find_all('a', class_='noline'):
   if 'Fantasy' in link.get('href'):
      links.append(f"{Base_url}{link.get('href')}")

# Scrape the winning numbers for each monthly results page
winning_numbers = []
for link in links:
    response = requests.get(link)
    content = response.content
    soup = BeautifulSoup(content, 'html.parser')
    for tag in soup.find_all('div', class_='ball blue5 fcblack1'):
        numbers = tag.text.strip().split()
        winning_numbers.append(numbers)

# Write the winning numbers to a file
with open('winning_numbers.txt', 'w') as Nums:
    for winners in winning_numbers:
        Nums.write("%s\n" % winners)
    print('Done')

The last thing I need to figure out is how to format the data that's been scraped. Currently every digit (01,15,02,10, etc) is considered it's own string I think? So it's being written to the document via

 Nums.write("%s\n" % winners)

and it's format is vertical. After every string it creates a new line, which I think I understand why. It's the %s\n, but I want it to create a new line every 5, or I guess it would be every 10 numbers because each string has two digits in it. My solution was to try something like

Nums.write('%s %s %s %s %s\n' % winners)

but I get a TypeError: not enough arguments in string.

I appreciate being pointed in the right direction please. I'm thinking may possibly use f-strings, or format(), but am unsure if those will work like how I want them to.

anyway thanks for all the help.
