UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
)
```

#### 由另一個模型內容建立 Pydantic 模型 { #a-pydantic-model-from-the-contents-of-another }

如上例我們從 `user_in.model_dump()` 得到 `user_dict`，以下程式碼：

```Python
user_dict = user_in.model_dump()
UserInDB(**user_dict)
```

等同於：

```Python
UserInDB(**user_in.model_dump())

name: build

  push:
    branches:
      - master

  GRADLE_OPTS: "-Xmx4g -Dorg.gradle.daemon=false -Dkotlin.incremental=false"

invalid requests.

Example Limitations

* Does not allow GET with a body.
* Cache is not an interface with alternative implementations.

Get a URL
---------

This program downloads a URL and prints its contents as a string. [Full source][get_example].

```java
OkHttpClient client = new OkHttpClient();

String run(String url) throws IOException {
  Request request = new Request.Builder()
      .url(url)
      .build();

        result = (result + (byteN and 0b0111_1111)) shl 7
      } else {
        return result + byteN
      }
    }
  }

  /** Read a value as bytes without interpretation of its contents. */
  fun readUnknown(): ByteString = source.readByteString(bytesLeft)

  override fun toString(): String = path.joinToString(separator = " / ")

  companion object {
    /**

      mutableNetwork.addEdge(endpoints, edge);
      return this;
    }

    /**
     * Returns a newly-created {@code ImmutableNetwork} based on the contents of this {@code
     * Builder}.
     */
    public ImmutableNetwork<N, E> build() {
      return ImmutableNetwork.copyOf(mutableNetwork);
    }
  }

首先要注意的是，我们定义了一个带有 `yield` 的异步函数。这与带有 `yield` 的依赖项非常相似。

{* ../../docs_src/events/tutorial003_py310.py hl[14:19] *}

这个函数在 `yield` 之前的部分，会在应用启动前执行。

剩下的部分在 `yield` 之后，会在应用完成后执行。

### 异步上下文管理器 { #async-context-manager }

如你所见，这个函数有一个装饰器 `@asynccontextmanager`。

它将函数转化为所谓的“**异步上下文管理器**”。

{* ../../docs_src/events/tutorial003_py310.py hl[1,13] *}

在 Python 中，**上下文管理器**是一个你可以在 `with` 语句中使用的东西，例如，`open()` 可以作为上下文管理器使用。
