Python Code Examples

Example for Personal Blog Platform (Django)

        
            from django.db import models

            class Post(models.Model):
                title = models.CharField(max_length=100)
                content = models.TextField()
                created_at = models.DateTimeField(auto_now_add=True)

                def __str__(self):
                    return self.title
        
    

Example for RESTful API (Flask)

        
            from flask import Flask, jsonify, request

            app = Flask(__name__)

            books = []

            @app.route('/books', methods=['GET', 'POST'])
            def manage_books():
                if request.method == 'POST':
                    book = request.get_json()
                    books.append(book)
                    return jsonify(book), 201
                return jsonify(books)

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

Example for E-commerce Website (Django)

        
            from django.urls import path
            from . import views

            urlpatterns = [
                path('products/', views.product_list, name='product_list'),
                path('products//', views.product_detail, name='product_detail'),
            ]
        
    

Example for Real-Time Chat Application (FastAPI)

        
            from fastapi import FastAPI, WebSocket

            app = FastAPI()

            @app.websocket("/ws")
            async def chat(websocket: WebSocket):
                await websocket.accept()
                while True:
                    message = await websocket.receive_text()
                    await websocket.send_text(f"Message text was: {message}")
        
    

Real-World Applications

Python web development is widely applied in various domains:
