Website blocker — Python Technical Interview Questions & Answers

Website blocker

Website blocker

  • Website blocker is a practical Python topic. Explain the job in school English, then the first three steps you would actually do.
  • Website blocker in practice: Pygame = game loop + window. CGI = old web scripts (today: Flask). Design patterns = reusable class shapes (singleton, factory) — only when the problem needs them. Deploy = put the script on Linux/Windows with venv + a start command. IDE = VS Code / PyCharm to edit and run.
  • For Website blocker always: venv, requirements.txt, don’t commit secrets.
  • Website blocker — output: block. Real blocker edits the OS hosts file — same set check.
