Projects and Applications in Python Web Development

Key Projects

Personal Portfolio Website: Create a dynamic personal site using Flask to showcase projects, skills, and experiences.
E-commerce Platform: Develop a fully functional e-commerce application using Django, incorporating user authentication and payment processing.
Blog Application: Build a blog website with features like post creation, editing, and commenting using Pyramid.
RESTful API Service: Create a REST API backend with FastAPI to manage user data and serve a front-end application.

Python Code Examples

1. Personal Portfolio Website with Flask

        
from flask import Flask, render_template

app = Flask(__name__)

@app.route('/')
def home():
    return render_template('index.html')

if __name__ == '__main__':
    app.run(debug=True)

2. E-commerce Platform with Django

        
from django.db import models

class Product(models.Model):
    name = models.CharField(max_length=100)
    price = models.DecimalField(max_digits=10, decimal_places=2)
    description = models.TextField()
    
    def __str__(self):
        return self.name

3. Blog Application with Pyramid

        

from pyramid.config import Configurator

from pyramid.response import Response
def homepage(request):

    return Response("
Welcome to my blog!
")
if __name__ == '__main__':

    with Configurator() as config:

        config.add_route('home', '/')

        config.add_view(homepage, route_name='home')

        app = config.make_wsgi_app()
Real-World Applications
