Example Code for Personal Blog (Flask)
from flask import Flask, render_template, request, redirect, url_for
app = Flask(__name__)
posts = []
@app.route('/')
def index():
return render_template('index.html', posts=posts)
@app.route('/add', methods=['POST'])
def add_post():
post_content = request.form.get('content')
posts.append(post_content)
return redirect(url_for('index'))
if __name__ == '__main__':
app.run(debug=True)
Example Code for E-commerce Website (Django)
from django.shortcuts import render
