it doesn't work I put in a file named templates it can find the file but it still doesn't work? thanks

add.html

<!doctype html>
<html>
<head>
<title> hello world </title>
<body>
<h1>{{ num1 }}+{{ num2 }} = {{num1 + num2}} </h1>

</body>
</html>

heres is shoplist.py

from flask import Flask
from flask import render_template

app = Flask(__name__)


@app.route('/')
@app.route('/<name>')
def index(name="rodney"):
    return "hello from {}".format(name)



@app.route('/add/<int:num1>/<int:num2>')
@app.route('/add/<float:num1>/<float:num2>')
@app.route('/add/<int:num1>/<float:num2>')
@app.route('/add/<float:num1>/<int:num2>')
def add(num1,num2):
    context = {'num1':num1, 'num2':num2}
    return render_template("add.html",**context)


app.run(debug=True,port=7000,host="0.0.0.0")

Verifying you have files set up as:

./shoplist.py
./templates/add.html

Can you explain what isn't working? What are you trying and what is the result?

From the Flask Docs' Quickstart:

Flask will look for templates in the templates folder. So if your application is a module, this folder is next to that module, if it’s a package it’s actually inside your package:

Case 1: a module:

/application.py
/templates
    /hello.html

Case 2: a package:

/application
    /__init__.py
    /templates
        /hello.html
