Simple Blog Application with Flask

        
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():
    post = request.form.get('post')
    posts.append(post)
    return redirect('/')

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

Building a Personal Portfolio with Django

        
from django.shortcuts import render

def portfolio(request):
    return render(request, 'portfolio.html')

Creating a RESTful API with Flask

        
from flask import Flask, jsonify

app = Flask(__name__)

@app.route('/api/data', methods=['GET'])
def get_data():
    sample_data = {'name': 'John', 'age': 30}
    return jsonify(sample_data)

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

Real-World Applications
