Projects and Applications in Python Web Development

Key Projects

• Personal Blogging Platform: Build a simple blogging platform using Flask. Users can register, create, edit, and delete blog posts.
• E-commerce Dashboard: Create a dashboard for an e-commerce site with Django, allowing for product management, sales tracking, and customer management.
• RESTful API: Develop a RESTful API for managing a library database using FastAPI, providing CRUD operations for books, authors, and users.
• Social Media App: Create a small-scale social media application where users can post updates, follow others, and like posts using Pyramid.

Python Code Examples

Personal Blogging Platform – Flask Example

            
from flask import Flask, render_template, request, redirect, url_for

app = Flask(__name__)

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

@app.route('/post', methods=['POST'])
def create_post():
    # Logic to create a blog post
    return redirect(url_for('index'))

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

E-commerce Dashboard – Django Example

            
from django.db import models

class Product(models.Model):
    name = models.CharField(max_length=100)
    price = models.DecimalField(max_digits=10, decimal_places=2)

class Order(models.Model):
    product = models.ForeignKey(Product, on_delete=models.CASCADE)
    quantity = models.IntegerField()
            
        

RESTful API – FastAPI Example

            
from fastapi import FastAPI

app = FastAPI()

@app.get("/books/")
def read_books():
    return [{"title": "Book 1"}, {"title": "Book 2"}]

@app.post("/books/")
def create_book(book: dict):
    return book
            
        

Social Media App – Pyramid Example

            
from pyramid.config import Configurator
from pyramid.response import Response

def home_view(request):
    return Response('Welcome to the Social Media App!')

if __name__ == '__main__':
    with Configurator() as config:
        config.add_route('home', '/')
        config.add_view(home_view, route_name='home')
        app = config.make_wsgi_app()
    from wsgiref.simple_server import make_server
    server = make_server('0.0.0.0', 6543, app)
    server.serve_forever()
