## Overview

BDIX_Tester_py is a command-line checker that tests a supplied list of ISP-local server URLs and saves those returning HTTP 200. The main workflow is in bdix.py: it obtains the URL list if needed, prompts for a timeout, checks each server, and writes working URLs to data.txt. The README documents the checker’s purpose; the sampled source shows its implementation. The local list and output are runtime files, not present in the supplied tree.

Main entry points: [`bdix.py`](https://github.com/shantanudeyanik/bdix_tester_py/blob/main/bdix.py) (BDIX checker)
