Unable to put different text files creating different subfolders within a main folder

Question

I've written a script in python to scrape the first five titles of different posts from a webpage and then write the titles in individual text files and put them in five different subfolders within a desktop folder DataStorage.

Currently my following script can parse the titles of five posts and write them in five different text files and put them in a desktop folder DataStorage.

How can I create five different subfolders within a main folder and put the text files in concerning subfolders?

This is my attempt so far:

import os
import requests
from bs4 import BeautifulSoup

url = "https://stackoverflow.com/questions/tagged/web-scraping"

dirf = r"C:\Users\WCS\Desktop\DataStorage" #The main folder in desktop
if not os.path.exists(dirf):os.makedirs(dirf)
os.chdir(dirf)

res = requests.get(url)
soup = BeautifulSoup(res.text,"lxml")
for item in soup.select(".summary .question-hyperlink")[:5]:
    filename = item.text.split(" ")[0]
    with open(filename+'.txt','w', encoding='utf-8') as filename:
        filename.write(item.text)

The following might work

import os
import requests
from bs4 import BeautifulSoup

url = "https://stackoverflow.com/questions/tagged/web-scraping"

dirf = r"C:\Users\WCS\Desktop\DataStorage"  # The main folder in desktop
if not os.path.exists(dirf):
    os.makedirs(dirf)
os.chdir(dirf)

res = requests.get(url)
soup = BeautifulSoup(res.text, "lxml")
for item in soup.select(".summary .question-hyperlink")[:5]:
    filename = item.text.split(" ")[0]
    curr_dir = os.path.join(dirf, filename)
    os.makedirs(curr_dir)
    filepath = os.path.join(curr_dir, filename+'.txt')
    with open(filepath, 'w', encoding='utf-8') as f:
        f.write(item.text)
