```Python
from datetime import date

from pydantic import BaseModel

# Declare a variable as a str
# and get editor support inside the function
def main(user_id: str):
    return user_id


# A Pydantic model
class User(BaseModel):
    id: int
    name: str
    joined: date
```

Sau đó có thể được sử dụng:

```Python

```Python
from datetime import date

from pydantic import BaseModel

# Déclare une variable comme étant une str
# et profitez de l'aide de votre IDE dans cette fonction
def main(user_id: str):
    return user_id


# Un modèle Pydantic
class User(BaseModel):
    id: int
    name: str
    joined: date
```
Qui peuvent ensuite être utilisés comme cela:

```Python

    val thread =
      Thread {
        try {
          call.execute()
          throw AssertionError()
        } catch (expected: IOException) {
        }
      }
    thread.start()
    return thread
  }

  private fun newRequest(url: String): Request = Request.Builder().url(url).build()

  private fun newRequest(
    url: String,
    tag: String,
  ): Request =
    Request

        assertTrue(laterAge >= 200, "Age should increase after delay");
    }

    @Test
    public void testKeyAgeNonExistent() {
        assertEquals(-1, keyManager.getKeyAge("non-existent"), "Non-existent key should return -1 for age");
    }

    @Test
    public void testConfigureKeyRotation() {
        // Test that configuration doesn't throw
        keyManager.configureKeyRotation(60000);

`HTTPException`, ao fundo, nada mais é do que a conjunção entre uma exceção comum do Python e informações adicionais relevantes para APIs.

E porque é uma exceção do Python, você não **retorna** (return) o `HTTPException`, você lança o (raise) no seu código.

```Python
from datetime import date

from pydantic import BaseModel

# Объявляем параметр user_id с типом `str`
# и получаем поддержку редактора внутри функции
def main(user_id: str):
    return user_id


# Модель Pydantic
class User(BaseModel):
    id: int
    name: str
    joined: date
```

Это можно использовать так:

```Python

            "coverageArch" to arch.name.lowercase(),
            "coverageJvmVendor" to testJvmVendor,
            "coverageJvmVersion" to "java$testJvmVersion",
        )
    return (
        listOf(
            "-PtestJavaVersion=$testJvmVersion",
            "-PtestJavaVendor=$testJvmVendor",
        ) +
            buildScanTags.map { buildScanTagParam(it) } +

		// Valid, existing bucket, delimiter not supported, returns empty values (Test number 8-9).
		{bucketNames[0], "", "", "", "*", 0, ListMultipartsInfo{Delimiter: "*"}, nil, true},
		{bucketNames[0], "", "", "", "-", 0, ListMultipartsInfo{Delimiter: "-"}, nil, true},
		// If marker is *after* the last possible object from the prefix it should return an empty list.
		{
			bucketNames[0], "Asia", "europe-object", "", "", 0,

                private static final long serialVersionUID = 1L;

                @Override
                public Integer getSuggestSystemMonitorIntervalAsInteger() {
                    return 60;
                }
            };
            ComponentUtil.setFessConfig(mockConfig);

        } catch (Exception e) {
            // Ignore setup errors in test environment
        }
    }

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```
