if __name__ == "__main__": main() | Step | What the script does | Why it matters | |------|----------------------|----------------| | Fetch page | requests.get() with a real browser‑like User‑Agent → Zippyshare returns the normal HTML (instead of a “bot blocked” page). | Some hosts reject generic Python agents. | | Parse the <a id="dlbutton"> element | BeautifulSoup extracts the href attribute, which contains a JavaScript expression that builds the final URL. | The real URL is not present in the static HTML. | | Extract parts with a regex | The pattern separates the static prefix, the arithmetic expression, and the suffix (the filename). | Allows us to evaluate the only numeric part safely. | | Safe eval | Strips everything except digits and +‑*/%() then eval s it in a sandboxed __builtins__=None environment. | Prevents arbitrary code execution while still handling the simple maths Zippyshare uses. | | Re‑assemble the full URL | urllib.parse.urljoin resolves the relative path against the original domain. | Gives a direct, one‑step download link (e.g. https://www20.zippyshare.com/d/abcd1234/12345/file.zip ). | | (Optional) Download | Streams the file in 8 KB chunks, shows a live progress bar, and writes it to the requested directory. | Handles large files without exhausting RAM. | 4.
