Python Code Examples

Flask Blog Application Example

        
from flask import Flask, render_template, request

app = Flask(__name__)

@app.route('/')
def home():
    return render_template('home.html')

@app.route('/post', methods=['POST'])
def post():
    title = request.form['title']
    content = request.form['content']
    # Save post to database here
    return render_template('post.html', title=title, content=content)

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

Django eCommerce Store Example

        
from django.shortcuts import render
from .models import Product

def product_list(request):
    products = Product.objects.all()
    return render(request, 'product_list.html', {'products': products})

RESTful API Example with Flask

        
from flask import Flask, jsonify

app = Flask(__name__)

data = {'message': 'Hello, World!'}

@app.route('/api', methods=['GET'])
def api():
    return jsonify(data)

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