Python Code Examples

Personal Blog Example with Django

        
            from django.db import models
            from django.contrib.auth.models import User

            class Post(models.Model):
                title = models.CharField(max_length=100)
                content = models.TextField()
                created_at = models.DateTimeField(auto_now_add=True)
                author = models.ForeignKey(User, on_delete=models.CASCADE)

                def __str__(self):
                    return self.title
        
    

To-Do List Application with Flask

        
            from flask import Flask, request, jsonify

            app = Flask(__name__)
            tasks = []

            @app.route('/tasks', methods=['GET', 'POST'])
            def manage_tasks():
                if request.method == 'POST':
                    task = request.json
                    tasks.append(task)
