Python Code Examples

Simple Flask Blog Application

        
from flask import Flask, render_template, request, redirect

app = Flask(__name__)
posts = []

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

@app.route('/add', methods=['POST'])
def add():
    post_content = request.form.get('content')
    posts.append(post_content)
    return redirect('/')

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

Django Task Management App Example

        
from django.db import models
from django.urls import reverse

class Task(models.Model):
    title = models.CharField(max_length=100)
    completed = models.BooleanField(default=False)

    def get_absolute_url(self):
        return reverse('task_list')
        
    

Flask RESTful API Example

        
from flask import Flask, jsonify, request

app = Flask(__name__)

tasks = []

@app.route('/tasks', methods=['GET', 'POST'])
def handle_tasks():
    if request.method == 'POST':
        task = request.json
        tasks.append(task)
        return jsonify(task), 201
    return jsonify(tasks)

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