Python Web Development Roadmap: From Flask to Production

The Stack You'll Learn

• Flask — the micro-framework to start with.
• FastAPI — modern, async, typed.
• SQLite → PostgreSQL — storage.
• HTML/CSS/JS — for the front end.

Month 1 — Flask Basics

from flask import Flask
app = Flask(__name__)

@app.route("/")
def home():
    return "Hello, PyForm!"

Month 2 — Templates and Forms

Jinja2 templates, WTForms, sessions, flash messages.

Month 3 — Database + ORM

SQLAlchemy basics, migrations with Alembic.

Month 4 — Auth + APIs

Login, logout, password hashing, building REST endpoints with FastAPI.

Month 5 — Deployment

Deploy to Render or Railway. Configure environment variables, static files, HTTPS.

Month 6 — Your SaaS

Build one real product. Share with friends. Get 10 users before moving on.
