Bạn viết chuẩn Python với kiểu dữ liệu như sau:

```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
```

  }

  public void testWildcardSubtypes() throws Exception {
    new WildcardSubtypingTests().testAllDeclarations();
  }

  /**
   * This test reproduces the bug in canonicalizeWildcardType() when the type variable is
   * recursively bounded.
   */
  public void testRecursiveWildcardSubtypeBug() throws Exception {
    Exception e =
        assertThrows(

Sie schreiben Standard-Python mit Typen:

```Python
from typing import List, Dict
from datetime import date

from pydantic import BaseModel

# Deklarieren Sie eine Variable als ein `str`
# und bekommen Sie Editor-Unterstütung innerhalb der Funktion
def main(user_id: str):
    return user_id


# Ein Pydantic-Modell
class User(BaseModel):
    id: int
    name: str

You write standard Python with types:

```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
```

  }

  public void testWildcardSubtypes() throws Exception {
    new WildcardSubtypingTests().testAllDeclarations();
  }

  /**
   * This test reproduces the bug in canonicalizeWildcardType() when the type variable is
   * recursively bounded.
   */
  public void testRecursiveWildcardSubtypeBug() throws Exception {
    Exception e =
        assertThrows(

### Paso 2: crea una "instance" de `FastAPI`

{* ../../docs_src/first_steps/tutorial001.py hl[3] *}

Aquí la variable `app` será una "instance" de la clase `FastAPI`.

Este será el punto principal de interacción para crear toda tu API.

### Paso 3: crea una *path operation*

#### Path

$ source .venv/Scripts/activate
```

이 명령어는 이후에 실행될 명령어에서 사용될 [환경 변수](environment-variables.md){.internal-link target=_blank} 몇 개를 생성하거나 수정합니다.

이 변수들 중 하나가 바로 `PATH` 변수입니다.

/// tip | 팁

`PATH` 환경 변수에 대해 더 알고 싶다면 [환경 변수 문서의 PATH 환경 변수 섹션](environment-variables.md#path-environment-variable){.internal-link target=_blank}을 참고하세요.

///

Stellen Sie sich vor, der Parameter soll `item-query` sein.

Wie in:

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

Aber `item-query` ist kein gültiger Name für eine Variable in Python.

Am ähnlichsten wäre `item_query`.

Aber Sie möchten dennoch exakt `item-query` verwenden.

Dann können Sie einen `alias` deklarieren, und dieser Alias wird verwendet, um den Parameter-Wert zu finden:

```bash helm install --set existingSecret=my-minio-secret minio/minio ``` The following fields are expected in the secret: | .data.<key> in Secret | Corresponding variable | Description | Required | |:-------- | `rootUser` | `rootUser` | Root user. | yes | | `rootPassword` | `rootPassword` | Root password. | yes | All corresponding variables will be ignored in values file. Configure TLS ---------- To enable TLS for MinIO containers, acquire TLS certificates from a CA or create self-signed certificates....

Эта команда создаст или изменит некоторые [переменные окружения](environment-variables.md){.internal-link target=_blank}, которые будут доступны для последующих команд.

Одной из таких переменных является `PATH`.
