Python Flask Basics Welcome to Flask First Steps

What am I doing wrong in the first step?

this is my code

from flask import Flask
from flask import render_template

app = Flask(__name__)

def index():
    return render_template("index.html")

app.run(debug=True, host="", port=8000)

When I run it at first and launched it in the browser it was ok, I could view my bear... but now when I'm redoing it again, when I run it I get this error all the time!!

werkzeug.routing.BuildError: ('save', {}, None)

Cannot see anything wrong with your code it works fine on my machine. Have you got any other views apart from index?

Thanks Andreas I figured out what was wrong. My "index.html" had a problem causing the whole app not to run
