Python Code Examples

Blog Application Example with 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

To-Do List App Example with Flask

        
            from flask import Flask, render_template, request, redirect
            
            app = Flask(__name__)
            tasks = []

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

            @app.route('/add', methods=['POST'])
            def add_task():
                task = request.form.get('task')
                tasks.append(task)
                return redirect('/')
