我们用的是冒号（`:`），不是等号（`=`）。

而且添加类型提示一般不会改变原来的运行结果。

现在假设我们又一次正在创建这个函数，这次添加了类型提示。

在同样的地方，通过 `Ctrl+Space` 触发自动补全，你会发现：

这样，你可以滚动查看选项，直到你找到看起来眼熟的那个：

## 更多动机

下面是一个已经有类型提示的函数：

```Python hl_lines="1"
{!../../../docs_src/python_types/tutorial003.py!}
```

<img src="/img/python-types/image02.png">

⏮️ 👈, 👆 💪 📜, 👀 🎛, ⏭ 👆 🔎 1️⃣ 👈 "💍 🔔":

<img src="/img/python-types/image03.png">

## 🌅 🎯

✅ 👉 🔢, ⚫️ ⏪ ✔️ 🆎 🔑:

```Python hl_lines="1"
{!../../../docs_src/python_types/tutorial003.py!}
```

↩️ 👨‍🎨 💭 🆎 🔢, 👆 🚫 🕴 🤚 🛠️, 👆 🤚 ❌ ✅:

일반적으로 타입힌트를 추가한다고 해서 특별하게 어떤 일이 일어나지도 않습니다.

그렇지만 이제, 다시 함수를 만드는 도중이라고 생각해봅시다. 다만 이번엔 타입 힌트가 있습니다.

같은 상황에서 `Ctrl+Space`로 자동완성을 작동시키면,

<img src="/img/python-types/image02.png">

아래와 같이 "그렇지!"하는 옵션이 나올때까지 스크롤을 내려서 볼 수 있습니다:

<img src="/img/python-types/image03.png">

## 더 큰 동기부여

아래 함수를 보면, 이미 타입 힌트가 적용되어 있는 걸 볼 수 있습니다:

```Python hl_lines="1"
{!../../../docs_src/python_types/tutorial003.py!}
```

	// +optional
	AvailableReplicas int32
}

// StatefulSetConditionType describes the condition types of StatefulSets.
type StatefulSetConditionType string

// TODO: Add valid condition types for Statefulsets.

// StatefulSetCondition describes the state of a statefulset at a certain point.
type StatefulSetCondition struct {
	// Type of statefulset condition.

	// the memory manager will assume that only 9Gi is available for allocation.
	// You can specify a different amount of NUMA node and memory types.
	// You can omit this parameter at all, but you should be aware that the amount of reserved memory from all NUMA nodes

An derselben Stelle versuchen Sie, die Autovervollständigung mit „Strg+Leertaste“ auszulösen, und Sie sehen:

<img src="/img/python-types/image02.png">

Hier können Sie durch die Optionen blättern, bis Sie diejenige finden, bei der es „Klick“ macht:

<img src="/img/python-types/image03.png">

## Mehr Motivation

Sehen Sie sich diese Funktion an, sie hat bereits Typhinweise:

```Python hl_lines="1"

    * In requests and responses, handled the same as a `float`.
* You can check all the valid pydantic data types here: <a href="https://docs.pydantic.dev/latest/usage/types/types/" class="external-link" target="_blank">Pydantic data types</a>.

## Example

Here's an example *path operation* with parameters using some of the above types.

=== "Python 3.10+"

    ```Python hl_lines="1  3  12-16"

type CrossVersionObjectReference struct {
	// kind is the kind of the referent; More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds"
	Kind string

	// name is the name of the referent; More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names
	Name string

	// apiVersion is the API version of the referent

type CrossVersionObjectReference struct {
	// Kind of the referent; More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
	Kind string `json:"kind" protobuf:"bytes,1,opt,name=kind"`
