Python PostgreSQL Flask GUI App - Build and Publish with Live Database! 🚀

Описание: Most full-stack tutorials talk theory for hours before you deploy anything — but in this one: we’re building, learning and publishing a fully functional GUI app in 20 minutes!! ⏰
In this hands-on tutorial, we take a static "Hello World" webpage (02:47) and transform it into a beautiful Flask and PostgreSQL dynamic application with a proper SQL database (03:07).
A production ready app that you can publish effortlessly (17:52) and share with the world! 🌍🚀

By the end of this video you'll have more than just code — you'll have you own production-ready social media app running live on a hosting platform named Sevalla — for free!! 😱😱😱 (checkout pinned comment for more detail)

💻 Environment Setup:
--------------------------------------------
conda create -n social_env python=3.12 flask
conda activate social_env
pip install psycopg

🗄️ Example SQL Table Creation:
--------------------------------------------
CREATE TABLE user_profiles(
username VARCHAR(20) PRIMARY KEY,
full_name TEXT NOT NULL,
photo_path TEXT,
bio TEXT,
country TEXT,
date_of_birth DATE NOT NULL
);

⚙️ Example Database Connection:
--------------------------------------------
import psycopg
with psycopg.connect(DB_URL) as connection:
cursor = connection.cursor()
cursor.execute("SELECT * FROM user_profiles;")
results = cursor.fetchall()

If you’ve ever felt intimidated by databases or backend development — this video will change that. You’ll see that full-stack isn’t about memorizing syntax… it’s about understanding the flow. 😎
