Use more pythonic string format

Description

Tank you a lot for this book, it is a great source of inspiration and make the exact bridge i was missing between clean architecture and working with a web framework and ORM.

That being said, i think you may use the string format in a more pythonic (and expressive) way like this:

setup = {
    "dbname": "rentomaticdb",
    "user": "rentomatic",
    "host": "localhost",
}

conn_str = "postgresql+psycopg2://{user}@{host}/{dbname}".format(**setup)

Hi @yobuntu thanks for the suggestion. I will add this in the second edition of the book that I'm finalising this month, hopefully it will be out for Christmas. I'll keep this open until it has been properly addressed, anyway
