from pydantic import BaseModel

# Declara una variable como un str
# y obtiene soporte del editor dentro de la función
def main(user_id: str):
    return user_id


# Un modelo de Pydantic
class User(BaseModel):
    id: int
    name: str
    joined: date
```

Que luego puede ser usado como:

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {

            !item.equals(item.toString()));
      }
    }
  }

  /**
   * Class used to test whether equals() correctly handles an instance of an incompatible class.
   * Since it is a private inner class, the invoker can never pass in an instance to the tester
   */
  private enum NotAnInstance {
    EQUAL_TO_NOTHING;
  }

 * @JvmField @Rule val serverRule = MockWebServerRule()
 * ```
 */
class MockWebServerRule : ExternalResource() {
  val server: MockWebServer = MockWebServer()

  override fun before() {
    try {
      server.start()
    } catch (e: IOException) {
      throw RuntimeException(e)
    }
  }

  override fun after() {
    server.close()
  }

=== Base classes for test cases

There are multiple base classes for tests:

* **`ESTestCase`**: The base class of all tests. It is typically extended
  directly by unit tests.
* **`ESSingleNodeTestCase`**: This test case sets up a cluster that has a
  single node.
* **`ESIntegTestCase`**: An integration test case that creates a cluster that
  might have multiple nodes.

  /**
   * A less abstract subclass of AbstractFuture. This can be used to optimize setFuture by ensuring
   * that {@link #get} calls exactly the implementation of {@link AbstractFuture#get}.

 *  Fix: Improve recovery from failed routes.
 *  Fix: Accommodate tunneling proxies that close the connection after an auth
    challenge.
 *  Fix: Use the proxy authenticator when authenticating HTTP proxies. This
    regression was introduced in OkHttp 3.0.
 *  Fix: Fail fast if network interceptors transform the response body such that
    closing it doesn't also close the underlying stream. We had a bug where
