import threading
import requests

def fetch_url(url):
    response = requests.get(url)
    print(f"{url}: {len(response.content)} bytes")

urls = ["http://example.com"] * 5
threads = []
for url in urls:
    t = threading.Thread(target=fetch_url, args=(url,))
    t.start()
    threads.append(t)

for t in threads:
    t.join()
