```Python
    first_name: str, last_name: str
```

Chính là nó.

Những thứ đó là "type hints":

{* ../../docs_src/python_types/tutorial002.py hl[1] *}


Đó không giống như khai báo những giá trị mặc định giống như:

```Python
    first_name="john", last_name="doe"
```

Nó là một thứ khác.

Chúng ta sử dụng dấu hai chấm (`:`), không phải dấu bằng (`=`).
