"id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```


/// info | 信息

`**second_user_data` 意思是：

直接将 `second_user_data` 字典的键和值作为 key-value 参数传入，等同于：`User(id=4, name="Mary", joined="2018-11-30")`

### 编辑器支持 { #editor-support }

整个框架都被设计得易于使用且直观，所有的决定都在开发之前就在多个编辑器上进行了测试，来确保最佳的开发体验。

import mockwebserver3.MockResponse
import mockwebserver3.MockWebServer

import mockwebserver3.SocketEffect.ShutdownConnection

import okhttp3.Cache.Companion.key
import okhttp3.Headers.Companion.headersOf
import okhttp3.MediaType.Companion.toMediaType
import okhttp3.MediaType.Companion.toMediaTypeOrNull
import okhttp3.RequestBody.Companion.toRequestBody

When there is an operation that will require waiting before giving the results and has support for these new Python features, you can code it like:

```Python
burgers = await get_burgers(2)
```

	}
	for wkey, wval := range want.Cache {
		gotv := got.Cache[wkey]
		if !equalAsJSON(gotv, wval) {
			t.Errorf("deserialize mismatch, key %v\nwant: %#v\ngot:  %#v", wkey, wval, gotv)
		}
	}
}

// equalAsJSON returns whether the values are equal when encoded as JSON.
func equalAsJSON(a, b any) bool {
	aj, err := json.Marshal(a)
	if err != nil {

          .isEqualTo(expected);
    }
  }

  public void testNullPointers() {
    NullPointerTester tester =
        new NullPointerTester()
            .setDefault(byte[].class, "secret key".getBytes(UTF_8))
            .setDefault(HashCode.class, HashCode.fromLong(0));
    tester.testAllPublicStaticMethods(Hashing.class);
  }

  public void testSeedlessHashFunctionEquals() throws Exception {

這代表：

* 變數 `items_t` 是一個有 3 個項目的 `tuple`，分別是 `int`、`int` 和 `str`。
* 變數 `items_s` 是一個 `set`，而其中每個項目都是 `bytes` 型別。

#### Dict { #dict }

定義 `dict` 時，你需要傳入 2 個以逗號分隔的型別參數。

第一個型別參數是 `dict` 的鍵（key）。

第二個型別參數是 `dict` 的值（value）：

{* ../../docs_src/python_types/tutorial008_py310.py hl[1] *}

這代表：

* 變數 `prices` 是個 `dict`：
    * 這個 `dict` 的鍵是 `str`（例如每個項目的名稱）。
