### Raise an `HTTPException` in your code { #raise-an-httpexception-in-your-code }

`HTTPException` is a normal Python exception with additional data relevant for APIs.

Because it's a Python exception, you don't `return` it, you `raise` it.

    Syntax of comments depends on the language of the code block.
    Raises ValueError if the blocks are not compatible (different languages or different number of lines).
