Oto, co warto mieć na uwadze podczas oceny pull requestu:

### Zrozum problem

* Najpierw upewnij się, że **rozumiesz problem**, który próbuje rozwiązać pull request. Może być osadzony w większym kontekście w GitHubowej dyskusji lub problemie.

* Jest też duża szansa, że pull request nie jest konieczny, ponieważ problem można rozwiązać w **inny sposób**. Wtedy możesz to zasugerować lub o to zapytać.

### Nie martw się stylem

* **Editor support**.
* **Type checks**.

...and **FastAPI** uses the same declarations to:

* **Define requirements**: from request path parameters, query parameters, headers, bodies, dependencies, etc.
* **Convert data**: from the request to the required type.
* **Validate data**: coming from each request:
    * Generating **automatic errors** returned to the client when the data is invalid.
* **Document** the API using OpenAPI:

### Kleine Fehler automatisch handhaben

Wenn beim Erstellen von Web-APIs mit FastAPI ein Fehler in unserem Code auftritt, wird FastAPI ihn normalerweise dem einzelnen Request zurückgeben, der den Fehler ausgelöst hat. 🛡

Der Client erhält für diesen Request einen **500 Internal Server Error**, aber die Anwendung arbeitet bei den nächsten Requests weiter, anstatt einfach komplett abzustürzen.

### Größere Fehler – Abstürze

3. The `Author` dataclass includes a list of `Item` dataclasses.

4. The `Author` dataclass is used as the `response_model` parameter.

5. You can use other standard type annotations with dataclasses as the request body.

    In this case, it's a list of `Item` dataclasses.

6. Here we are returning a dictionary that contains `items` which is a list of dataclasses.
