## Coroutines

**Coroutine** is just the very fancy term for the thing returned by an `async def` function. Python knows that it is something like a function that it can start and that it will end at some point, but that it might be paused ⏸ internally too, whenever there is an `await` inside of it.

```Python hl_lines="1"
async def get_burgers(number: int):
    # Mach Sie hier etwas Asynchrones, um die Burger zu erstellen
    return burgers
```

... statt mit `def`:

```Python hl_lines="2"
# Die ist nicht asynchron
def get_sequential_burgers(number: int):
    # Mach Sie hier etwas Sequentielles, um die Burger zu erstellen
    return burgers
```
