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)
