🐍 Flask 3-in-1 Demo

A single‑file Flask project that bundles three tiny apps behind one server: a password‑guessing game, a product data lookup, and a live user patcher. The goal is to showcase core Flask patterns—routing, form handling, redirects, and in‑memory data manipulation—using only Python.

✨ Features

• Zero dependencies beyond Flask itself
• Three independent flows exposed from the same app
  • Password Game – basic auth logic with redirects
  • Data Request – query‑string parsing & dynamic rendering
  • User Patcher – add or update records then render a live table
• Inline HTML/CSS so you don’t need Jinja templates while learning
• Hot‑reload ready via flask run or python app.py

🏃‍♂️ Quick start

# clone & enter
$ git clone https://github.com/your‑handle/flask‑3‑in‑1.git

# (optional) create a venv
$ python -m venv .venv && source .venv/bin/activate

# install Flask
$ pip install Flask

# run the dev server
$ python app.py  # -> http://127.0.0.1:5000
