Python Code Examples
Blog Application Setup with Django
from django.conf import settings
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
Simple RESTful API with Flask
from flask import Flask, jsonify, request
app = Flask(__name__)
tasks = []
@app.route('/tasks', methods=['GET'])
def get_tasks():
return jsonify(tasks)
@app.route('/tasks', methods=['POST'])
def add_task():
task = request.json
tasks.append(task)
return jsonify(task), 201
if __name__ == '__main__':
app.run(debug=True)
