I set up a flask project using VS2015. The code is as follows:

views.py:

from datetime import datetime
from flask import render_template
from flask import Flask
from FlaskWebProject1 import app

@app.route("/")
@app.route("/home")
def home():
    return render_template(
        "index.html",
        title="Home Page"
    )

@app.route("/greeting/<surname>/<lastname>")
def greeting(surname,lastname):
    return ("Hello "+surname+" "+lastname)

runserver.py:

"""
This script runs the FlaskWebProject1 application using a development server.
"""

from os import environ
from FlaskWebProject1 import app

if __name__ == "__main__":
    HOST = environ.get("SERVER_HOST", "localhost")
    try:
        PORT = int(environ.get("SERVER_PORT", "5555"))
    except ValueError:
        PORT = 5555
    app.run(host = "0.0.0.0", port = 8081, debug = False)

according to flask"s official tutorial:
