## Conversão de <abbr title="também conhecido como: serialização, parsing, marshalling">dados</abbr>

Se você rodar esse exemplo e abrir o seu navegador em <a href="http://127.0.0.1:8000/items/3" class="external-link" target="_blank">http://127.0.0.1:8000/items/3</a>, você verá a seguinte resposta:

import org.graalvm.nativeimage.hosted.RuntimeReflection

@AutomaticFeature
class TestRegistration : Feature {
  override fun beforeAnalysis(access: Feature.BeforeAnalysisAccess) {
    // Presumably needed for parsing the testlist.txt file.
    RuntimeClassInitialization.initializeAtBuildTime(access.findClassByName("kotlin.text.Charsets"))

    registerKnownTests(access)

    registerJupiterClasses(access)

user_dict = user_in.dict()
UserInDB(**user_dict)
```

would be equivalent to:

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

...because `user_in.dict()` is a `dict`, and then we make Python "unwrap" it by passing it to `UserInDB` prefixed with `**`.

So, we get a Pydantic model from the data in another Pydantic model.

#### Unwrapping a `dict` and extra keywords

      "p" -> path = value
      "q" -> query = value
      "f" -> fragment = value
      else -> throw IllegalArgumentException("unexpected attribute: $value")
    }
  }

  override fun toString(): String = format("Parsing: <%s> against <%s>", input!!, base!!)

  companion object {
    fun load(source: BufferedSource): List<WebPlatformUrlTestData> {
      val list = mutableListOf<WebPlatformUrlTestData>()
      while (true) {
