Is there a tutorial for running flask apps locally on windows?

I was able to import flask into IDLE in a virtual environment but cannot get the simple_app.py from the flask basics course to run, and have no idea how I would see it in the browser. I've tried looking online but can't find anything, if someone could explain or point me in the right direction I would greatly appreciate it!

My code from the first part of the Flask Basics course:

from flask import Flask

app = Flask(name)

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

@app.route('/add/<int:num1>/<int:num2>') @app.route('/add/<int:num1>/<float:num2>') @app.route('/add/<float:num1>/<int:num2>') @app.route('/add/<float:num1>/<float:num2>') def add(num1, num2): return '{} + {} = {}'.format(num1, num2, num1+num2)

app.run(debug=True, port=8000, host='0.0.0.0')
