## Path parameters with types

You can declare the type of a path parameter in the function, using standard Python type annotations:

```Python hl_lines="7"
{!../../docs_src/path_params/tutorial002.py!}
```

Você pode passar um `dict` ou um `list`, etc.
Esses tipos de dados são manipulados automaticamente pelo **FastAPI** e convertidos em JSON.

## Adicione headers customizados

Há certas situações em que é bastante útil poder adicionar headers customizados no HTTP error. Exemplo disso seria adicionar headers customizados para tipos de segurança.

اگر به یک یادآوری ۲ دقیقه ای در مورد نحوه استفاده از تایپ های پایتون دارید (حتی اگر از FastAPI استفاده نمیکنید) این آموزش کوتاه را بررسی کنید: [Python Types](python-types.md){.internal-link target=\_blank}.

شما پایتون استاندارد را با استفاده از تایپ ها مینویسید:

```Python
from datetime import date

from pydantic import BaseModel

# Declare a variable as a str

Cgo recognizes any use of a qualified identifier C.xxx and uses gcc to
find the definition of xxx.  If xxx is a type, cgo replaces C.xxx with
a Go translation.  C arithmetic types translate to precisely-sized Go
arithmetic types.  A C struct translates to a Go struct, field by
field; unrepresentable fields are replaced with opaque byte arrays.  A
C union translates into a struct containing the first union member and

    `BufferedSink` and a `ResponseBody` as an Okio `BufferedSource`. Standard
    `InputStream` and `OutputStream` access is also available.

 *  **New Call and Callback types** execute requests and receive their
    responses. Both types of calls can be canceled via the `Call` or the
    `OkHttpClient`.

 *  **URLConnection support has moved to the okhttp-urlconnection module.**
