Exercise #0: Test Flask Application

Launch the minimalistic Flask application and test it by making a request to it both from a browser (http://localhost:5000).

Exercise #1: Post code lookup service

Create a flask application that can look up location names based on the post code. Store the locations in a dictionary, e.g.,

postcodes = {
    "0001": "Oslo",
    "4036": "Stavanger",
    "4041": "Hafrsfjord",
    "7491": "Trondheim",
    "9019": "Tromsø"
}

If the user goes to the index page, return the text "Postcode lookup service. Example usage: /postcode/4041", where the example link should be generated automatically (using url_for()) and should be a link (<a href>...</a>)

If the post code exists, return the text "Post code {postcode} is {city}"

Otherwise return "Unknown post code ({postcode})"
