# Example code for a simple Flask To-Do List App

from flask import Flask, render_template, request, redirect

app = Flask(__name__)
todos = []

@app.route('/')
def index():
    return render_template('index.html', todos=todos)

@app.route('/add', methods=['POST'])
def add():
    new_todo = request.form['todo']
    todos.append(new_todo)
    return redirect('/')

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