```JSON
{"item_id": 5, "q": "somequery"}
```

আপনি ইতিমধ্যে একটি API তৈরি করেছেন যা:

- `/` এবং `/items/{item_id}` _paths_ এ HTTP অনুরোধ গ্রহণ করে।
- উভয় *path*ই `GET` অপারেশন নেয় ( যা HTTP _methods_ নামেও পরিচিত)।
- _path_ `/items/{item_id}`-এ একটি _path প্যারামিটার_ `item_id` আছে যা কিনা `int` হতে হবে।
- _path_ `/items/{item_id}`-এর একটি ঐচ্ছিক `str` _query প্যারামিটার_ `q` আছে।

### ক্রিয়াশীল API নির্দেশিকা নথি

### Recapitulando

Resumindo, você declara **uma vez** os tipos dos parâmetros, corpo etc. como parâmetros de função.

Você faz com tipos padrão do Python moderno.

Você não terá que aprender uma nova sintaxe, métodos ou classes de uma biblioteca específica etc.

Apenas **Python** padrão.

Por exemplo, para um `int`:

```Python
item_id: int
```

ou para um modelo mais complexo, `Item`:

```Python

Em python, você pode criar Gerenciadores de Contexto ao <a href="https://docs.python.org/3/reference/datamodel.html#context-managers" class="external-link" target="_blank"> criar uma classe com dois métodos: `__enter__()` e `__exit__()`</a>.

Você também pode usá-los dentro de dependências com `yield` do **FastAPI** ao utilizar `with` ou `async with` dentro da função da dependência:

```Python hl_lines="1-9  13"

    url =
      server.url(
        """/api/login?
      |user=test_user&
      |authentication=basic&
      |password=confidential_password&
      |authentication=rather simple login method
        """.trimMargin(),
      )
    val networkInterceptor =
      HttpLoggingInterceptor(networkLogs).setLevel(
        Level.BASIC,
      )
    networkInterceptor.redactQueryParams("user", "passWord")

   * the key is moved, deleted, or reinserted, it will account for that -- while not doing any extra
   * work if the key has not moved. One quirk: The {@link #getValue()} method can return {@code
   * null} even for a map which supposedly does not contain null elements, if the key is not present
   * when {@code getValue()} is called.
   */
  final class EntryForKey extends AbstractMapEntry<K, V> {

	}

	// Query string.
	queryStr := req.Form.Encode()

	// Get canonical request.
	canonicalRequest := getCanonicalRequest(extractedSignedHeaders, payload, queryStr, req.URL.Path, req.Method)

	// Get string to sign from canonical request.
	stringToSign := getStringToSign(canonicalRequest, date, signV4Values.Credential.getScope())

	// Get hmac signing key.

এটি একটি খুব সাধারণ প্রোগ্রাম।

কিন্তু এখন কল্পনা করুন যে আপনি এটি শুরু থেকে লিখছিলেন।

এক পর্যায়ে আপনি ফাংশনের সংজ্ঞা শুরু করেছিলেন, আপনার প্যারামিটারগুলি প্রস্তুত ছিল...

কিন্তু তারপর আপনাকে "সেই method কল করতে হবে যা প্রথম অক্ষরকে বড় হাতের অক্ষরে রূপান্তর করে"।

এটা কি `upper` ছিল? নাকি `uppercase`? `first_uppercase`? `capitalize`?

তারপর, আপনি পুরোনো প্রোগ্রামারের বন্ধু, এডিটর অটোকমপ্লিশনের সাহায্যে নেওয়ার চেষ্টা করেন।
