(1) Installing FLASK and Setting Your RPi WebServer

sudo apt-get update
sudo pip install Flask

(2) Create folder  
(2.0) cd Documents
(2.1)  mkdir rpiWebServer
(2.2)  cd rpiWebServer
(2.3)  mkdir static
(2.4) mkdir templates

(3)  Create helloWorld.py     

from flask import Flask
app = Flask(__name__) 
@app.route("/")
def hello():
    return "Hello World!" 

if __name__ == '__main__':
    app.run(debug=True, port=80, host='0.0.0.0')

 

The final folder “tree”, will look like:
