What happens when you try to build a web app with Flask… in 3 minutes?
Well… it works. But it gets awkward. Fast.
In this micro-speedrun of a tutorial, I’ll show you:
🚀 How to install Flask in one line
🧠 How to create your first route (/)
🔁 How to return JSON with a dynamic route (/check/int:num)
🔍 And how to tell if a number is even, odd, or prime — right in your browser
No HTML. No CSS. No distractions.
Just pure Python, a single file, and one slightly chaotic blind date with Flask.
👇 Build your own weird endpoint and tell me what happened.
