Setting Up Your Development Environment
1. Install Python
Get the latest version from python.org.
2. Create a Virtual Environment
This keeps your project dependencies organized:
python -m venv myenv
source myenv/bin/activate # Mac/Linux
myenv\Scripts\activate # Windows
3. Install Your Framework
pip install Django
# or
pip install flask
Building the Backend
Here’s a simple Flask example:
from flask import Flask
app = Flask(__name__)
@app.route(“/”)
def home():
return “Welcome to my Python website!”
if __name__ == “__main__”:
app.run(debug=True)
With Django, you’d start by running:
django-admin startproject mysite
The backend is where you define routes, manage data, and create business logic.
Integrating the Frontend
Python handles the logic, but HTML, CSS, and JavaScript create the look and feel.
- Use Bootstrap or Tailwind CSS for styling.
- Add React or Vue.js for interactive elements.
Serve static files properly to keep your site fast.
Database Setup and Management
Common options:
- SQLite — simple and included with Python.
- PostgreSQL — powerful and scalable.
- MySQL — widely supported.
Django comes with its own ORM, while Flask often uses SQLAlchemy.
User Authentication and Security
A few essentials:
- Always use HTTPS with SSL.
- Hash passwords with libraries like bcrypt.
- Avoid SQL injection by using ORM.
- Enable CSRF protection in forms.
Deploying Your Website
Popular hosting options:
- Heroku — easiest for beginners.
- PythonAnywhere — built for Python projects.
- AWS/DigitalOcean — for advanced scaling.
Always test locally before pushing live.
