Python Code Examples

Blog Application (Django)

        
            from django.shortcuts import render
            from .models import Post

            def blog_home(request):
                posts = Post.objects.all()
                return render(request, 'blog/home.html', {'posts': posts})
        
    

RESTful API (Flask)

        
            from flask import Flask, jsonify, request

            app = Flask(__name__)

            products = []

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

            @app.route('/products', methods=['POST'])
            def add_product():
                product = request.json
                products.append(product)
                return jsonify(product), 201

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

Real-Time Chat Application (FastAPI)

        
            from fastapi import FastAPI
            from fastapi.middleware.cors import CORSMiddleware

            app = FastAPI()
            app.add_middleware(
                CORSMiddleware,
                allow_origins=["*"],
                allow_credentials=True,
                allow_methods=["*"],
                allow_headers=["*"],
            )

            @app.get("/")
            async def read_root():
                return {"message": "Welcome to the chat application!"}
        
    

Real-World Applications

Python web development is employed across various industries, facilitating the creation of applications that enhance business operations and user experiences. Examples include:

• E-commerce Platforms: Many online stores utilize Django or Flask to manage product listings, customer accounts, and transactions.
• Social Media Integration: Applications often require complex backends that are developed using Python frameworks to handle user interactions efficiently.
• Data-Driven Applications: The ability to pull data from databases using ORM tools in Django makes it ideal for building applications that rely heavily on data.
• API Development: FastAPI is increasingly used in developing APIs that serve mobile applications and other web services, enabling seamless data exchange.
