### Est-ce que la concurrence est mieux que le parallélisme ? { #is-concurrency-better-than-parallelism }

Nope ! C'est ça la morale de l'histoire.

La concurrence est différente du parallélisme. C'est mieux sur des scénarios **spécifiques** qui impliquent beaucoup d'attente. À cause de ça, c'est généralement bien meilleur que le parallélisme pour le développement d'applications web. Mais pas pour tout.

This idea of **asynchronous** code described above is also sometimes called **"concurrency"**. It is different from **"parallelism"**.

**Concurrency** and **parallelism** both relate to "different things happening more or less at the same time".

But the details between *concurrency* and *parallelism* are quite different.

To see the difference, imagine the following story about burgers:

### Parallele Hamburger { #parallel-burgers }

Stellen wir uns jetzt vor, dass es sich hierbei nicht um „nebenläufige Hamburger“, sondern um „parallele Hamburger“ handelt.

Sie gehen los mit Ihrem Schwarm, um paralleles Fast Food zu bekommen.

### Eşzamanlılık ve Burgerler { #concurrency-and-burgers }

Yukarıda anlatılan **asenkron** kod fikrine bazen **"eşzamanlılık"** (concurrency) da denir. **"Paralellik"**ten (parallelism) farklıdır.

**Eşzamanlılık** ve **paralellik**, "aynı anda az çok birden fazla şeyin olması" ile ilgilidir.

Ama *eşzamanlılık* ve *paralellik* arasındaki ayrıntılar oldukça farklıdır.

如果你正在使用要求你以 `await` 語法呼叫的第三方函式庫，例如：

```Python
results = await some_library()
```

然後，使用 `async def` 宣告你的*路徑操作函式*：


```Python hl_lines="2"
