@Member#952511’s snippet is a concise way to fetch the raw HTTP response, but two practical points are worth adding for future readers. First, that pattern reflects Python‑2-era usage and only returns the server’s HTML (and any inline client scripts) — it does not execute JavaScript, so pages that build content in the browser will look incomplete. Second, character encoding and HTTP error handling need explicit attention rather than assuming one default.

A modern, more robust pattern (Python 3 + requests) combines sensible headers, timeouts, error checking and best‑effort charset detection:

import requests

try:
    resp = requests.get("https://example.com",
                        headers={"User-Agent": "Mozilla/5.0"},
                        timeout=10)
    resp.raise_for_status()
    resp.encoding = resp.apparent_encoding  # best-effort charset detection
    html = resp.text
    print(html[:500])
except requests.RequestException as err:
    print("Request failed:", err)

Sites that render content client‑side still require a browser runtime to get the final DOM. For those, a headless browser (Selenium, Playwright) or calling the same XHR/JSON endpoints the page uses is the correct approach. When exact bytes matter (images, downloads), work with resp.content and decode only after reliable detection (chardet/charset‑normalizer) with a safe fallback and errors='replace'.

Practical cautions: check Content-Type headers for charset hints, reuse a Session for multiple requests, set reasonable timeouts, follow redirects, verify TLS, and respect robots.txt and site terms. @M.S. was right to flag encoding — handling it explicitly avoids mangled text in international pages and makes the fetch resilient.
