Let's see how it looks in FastAPI. So I'm importing HTTP status because I like to use the status and not the number. And I'm going to use datetime. And I'm importing FastAPI and the HTTP exception for FastAPI, which I'm going to use for invalid parameters. I import the logs. This is the package with the dummy database that I wrote.
