def get_full_name(first_name: str, last_name: str):
    full_name = first_name.title() + " " + last_name.title()
    return full_name

def get_full_name(first_name, last_name):
    full_name = first_name.title() + " " + last_name.title()
    return full_name

Önceki sürümden sadece bir satırı değiştirelim.

Tam olarak bu parçayı, işlevin parametrelerini  değiştireceğiz:

```Python
    first_name, last_name
```

ve bu hale getireceğiz:

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

Bu kadar.

İşte bunlar "tip belirteçleri":

```Python hl_lines="1"
{!../../../docs_src/python_types/tutorial002.py!}
```

```Python
    first_name, last_name
```

para:

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

É isso aí.

Esses são os "type hints":

```Python hl_lines="1"
{!../../../docs_src/python_types/tutorial002.py!}
```

Isso não é o mesmo que declarar valores padrão como seria com:

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

É uma coisa diferente.

```Python
    first_name, last_name
```

a:

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

Eso es todo.

Esos son los "type hints":

```Python hl_lines="1"
{!../../../docs_src/python_types/tutorial002.py!}
```

No es lo mismo a declarar valores por defecto, como sería con:

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

Es algo diferente.

然后你尝试向程序员老手的朋友——编辑器自动补全寻求帮助。

输入函数的第一个参数 `first_name`，输入点号（`.`）然后敲下 `Ctrl+Space` 来触发代码补全。

但遗憾的是并没有起什么作用：

### 添加类型

让我们来修改上面例子的一行代码。

我们将把下面这段代码中的函数参数从：

```Python
    first_name, last_name
```

改成：

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

就是这样。

这些就是"类型提示"：

		{"p/", "url", "p/"},
		{"p/", "url", "p/"},
		{"~user", "url", "%7Euser"},
		{"*user", "url", "*user"},
		{"user+password", "url", "user%2Bpassword"},
		{"_user", "url", "_user"},
		{"firstname.lastname", "url", "firstname.lastname"},
	}
	for i, testCase := range testCases {
		t.Run(fmt.Sprintf("Test%d", i+1), func(t *testing.T) {
			outputText := s3EncodeName(testCase.inputText, testCase.encodingType)
