# Python 模式
|
|
|
|
> 本文档扩展了 [common/patterns.md](../common/patterns.md)，补充了 Python 特定的内容。
|
|
|
|
## 协议（鸭子类型）
|
|
|
|
```python
|
|
from typing import Protocol
|
|
|
|
class Repository(Protocol):
|
|
def find_by_id(self, id: str) -> dict | None: ...
|
|
def save(self, entity: dict) -> dict: ...
|
|
```
|
|
|
|
## 数据类作为 DTO
|
|
|
|
```python
|
|
from dataclasses import dataclass
|
|
|
|
@dataclass
|
|
class CreateUserRequest:
|
|
name: str
|
|
email: str
|
|
age: int | None = None
|
|
```
|
|
|
|
## 上下文管理器与生成器
|
|
|
|
* 使用上下文管理器（`with` 语句）进行资源管理
|
|
* 使用生成器进行惰性求值和内存高效迭代
|
|
|
