with ThreadPoolExecutor(max_workers=5) as executor: executor.map(download_one, urls) Some PDFs load via JavaScript (e.g., Google Docs viewer). Use selenium :

cookies = "sessionid": "your_session_cookie" with open("output

response = requests.get("https://secure-site.com/report.pdf", headers=headers, cookies=cookies, auth=("username", "password")) # Basic auth import requests url = "https://example.com/huge.pdf" response = requests.get(url, stream=True)

import requests Download and save a PDF url = "https://example.com/document.pdf" response = requests.get(url)

That’s it. But real PDF downloads can fail. Here’s the practical, copy-paste guide. import requests def download_pdf(url, filename): response = requests.get(url) response.raise_for_status() # Stop if error (404, 403, etc.) Here’s the practical, copy-paste guide

print(f"Saved: filename") download_pdf("https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf", "sample.pdf") 2. Handle Authentication & Headers (Many real PDFs) import requests headers = "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36"

driver.quit() | Problem | Solution | |--------|----------| | 403 Forbidden | Add User-Agent header | | Slow download | Use stream=True with chunking | | PDF is actually HTML (login page) | Check response.headers['content-type'] — should be application/pdf | | HTTPS certificate error | verify=False (not recommended, but works) | | URL redirects | requests follows them automatically |
