urlib - to use or not to use ( for web scraping )?

[Truman]

This code takes images from a page and prints them:

import os
import requests
from bs4 import BeautifulSoup

downloadDirectory = "downloaded"
baseUrl = "http://pythonscraping.com"

def getAbsoluteURL(baseUrl, source):
    if source.startswith("http://www."):
        url = "http://"+source[11:]
    elif source.startswith("http://"):
        url = source
    elif source.startswith("www."):
        url = source[4:]
        url = "http://"+source
    else:
        url = baseUrl+"/"+source
    if baseUrl not in url:
        return None
    return url 
	
def getDownloadPath(baseUrl, absoluteUrl, downloadDirectory):
	path = absoluteUrl.replace("www.", "")
	path = path.replace(baseUrl, "")
	path = downloadDirectory+path
	directory = os.path.dirname(path)
	if not os.path.exists(directory):
		os.makedirs(directory)
	return path 

html = requests.get("http://www.pythonscraping.com")
bsObj = BeautifulSoup(html.content, 'html.parser')
downloadList = bsObj.find_all(src=True)

now I want to download these images to the directory downloaded so I added this piece of code:

with open(fileUrl, getDownloadPath(baseUrl, fileUrl, downloadDirectory)) as out_file:
    out_file.write(fileUrl.content)

but I get this:

Error:

p.s. to add that execution of this code opened folder downloaded and empty folder img within it.
