### Override the `HTTPException` error handler { #override-the-httpexception-error-handler }

The same way, you can override the `HTTPException` handler.

For example, you could want to return a plain text response instead of JSON for these errors:

{* ../../docs_src/handling_errors/tutorial004_py39.py hl[3:4,9:11,25] *}

It could look like this:

```plaintext
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/custompython/bin
```

This way, when you type `python` in the terminal, the system will find the Python program in `/opt/custompython/bin` (the last directory) and use that one.

The same way, there are many compatible tools. Including code generation tools for many languages.

## Pydantic { #pydantic }

...and then Swagger UI won't show the syntax highlighting anymore:

## Change the Theme { #change-the-theme }

The same way you could set the syntax highlighting theme with the key `"syntaxHighlight.theme"` (notice that it has a dot in the middle):
