Projects and Applications in Python Web Development

Key Projects

• Blog Application: Develop a fully functional blog using Django where users can create, edit, and delete posts, comment on them, and tag them for easier categorization.
• RESTful API Service: Create a RESTful API using Flask that allows users to retrieve, create, and delete user profiles, demonstrating CRUD operations.
• Portfolio Website: Build a personal portfolio site with FastAPI to showcase projects, skills, and contact information with integrated user authentication.

Python Code Examples

Blog Application (Django)

            
# models.py
from django.db import models

class Post(models.Model):
    title = models.CharField(max_length=200)
    content = models.TextField()
    created_at = models.DateTimeField(auto_now_add=True)
    
# views.py
from django.shortcuts import render
from .models import Post

def blog_list(request):
    posts = Post.objects.all()
    return render(request, 'blog_list.html', {'posts': posts})
            
        

RESTful API Service (Flask)

            
from flask import Flask, jsonify, request

app = Flask(__name__)

users = []

@app.route('/users', methods=['GET'])
def get_users():
    return jsonify(users)

@app.route('/users', methods=['POST'])
def create_user():
    user = request.get_json()
    users.append(user)
    return jsonify(user), 201
            
        

Portfolio Website (FastAPI)

            
from fastapi import FastAPI

app = FastAPI()

@app.get("/portfolio/")
def read_portfolio():
    return {"projects": ["Project 1", "Project 2", "Project 3"], "contact": "[email protected]"}
            
        

Real-World Applications

Python web development is extensively utilized across various industries. Here are a few real-world applications:
