That `@something` syntax in Python is called a "decorator".

You put it on top of a function. Like a pretty decorative hat (I guess that's where the term came from).

A "decorator" takes the function below and does something with it.

In our case, this decorator tells **FastAPI** that the function below corresponds to the **path** `/` with an **operation** `get`.

It is the "**path operation decorator**".

Gryphon.  `Do you know why it's called a whiting?'

  `I never thought about it,' said Alice.  `Why?'

  `IT DOES THE BOOTS AND SHOES.' the Gryphon replied very
solemnly.

  Alice was thoroughly puzzled.  `Does the boots and shoes!' she
repeated in a wondering tone.

  `Why, what are YOUR shoes done with?' said the Gryphon.  `I
mean, what makes them so shiny?'
