### Input Model in Docs { #input-model-in-docs }

You can confirm that in the docs, the `description` field doesn't have a **red asterisk**, it's not marked as required:

<div class="screenshot">
<img src="/img/tutorial/separate-openapi-schemas/image01.png">
</div>

### Model for Output { #model-for-output }

But if you use the same model as an output, like here:

////

So, if you type:

<div class="termy">

```console
$ python
```

</div>

//// tab | Linux, macOS

The system will **find** the `python` program in `/opt/custompython/bin` and run it.

It would be roughly equivalent to typing:

<div class="termy">

```console
$ /opt/custompython/bin/python
```

</div>
