Because the editor knows the types of the variables, you don't only get completion, you also get error checks:

Now you know that you have to fix it, convert `age` to a string with `str(age)`:

{* ../../docs_src/python_types/tutorial004_py310.py hl[2] *}

## Declaring types { #declaring-types }

You just saw the main place to declare type hints. As function parameters.

    private String interpolatedTrimmed(String value, String context) {
        return getTrimmedValue(contentTransformer.transform(value, context));
    } // -- String interpolatedTrimmed( String, String )

Por exemplo, no arquivo `app/main.py`, você poderia ter uma linha como:

```
from app.routers import items
```

///

* O diretório `app` contém tudo. E possui um arquivo vazio `app/__init__.py`, então ele é um "pacote Python" (uma coleção de "módulos Python"): `app`.
* Ele contém um arquivo `app/main.py`. Como está dentro de um pacote Python (um diretório com um arquivo `__init__.py`), ele é um "módulo" desse pacote: `app.main`.

            buf.enc_ndr_short(0); /* context id */
