Python Code Examples

Example for Blog Application using Flask

        
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 create_post():
    title = request.form['title']
    content = request.form['content']
    # Save the post to the database (not implemented here)
    return f'Post titled "{title}" has been created!'

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

Example for E-commerce Store using Django

        
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})
