Create local website to test code

[lymacasm]

Find a way to display html code on a web browser from a local machine, without a specific web browser.

[lymacasm]

This is implemented in app.py, using Flask. The following code shows what produces the local browser:

app = Flask(__name__)
.
.
.
if __name__ == '__main__':
    port = int(os.environ.get('PORT', 5000))

    if port == 5000:
        app.debug = True

    app.run(host='0.0.0.0', port=port)

The local website can be accessed at http://localhost:5000/
