For example:

```Python
class Cat:
    def __init__(self, name: str):
        self.name = name


fluffy = Cat(name="Mr Fluffy")
```

In this case, `fluffy` is an instance of the class `Cat`.

And to create `fluffy`, you are "calling" `Cat`.

So, a Python class is also a **callable**.

    echo "Please remove the following extra licenses from $LICENSES_TARGET:"
    cat $BATS_TEST_TMPDIR/actual_extra_licenses
  fi

  if [[ -s $BATS_TEST_TMPDIR/actual_missing_licenses ]]; then
    echo "Please include the missing licenses for the following packages in $LICENSES_TARGET:"
    cat $BATS_TEST_TMPDIR/actual_missing_licenses
  fi

#!/usr/bin/env bash

# shellcheck disable=SC2120
exit_1() {
	cleanup

	for site in sitea siteb; do
		echo "$site server logs ========="
		cat "/tmp/${site}_1.log"
		echo "==========================="
		cat "/tmp/${site}_2.log"
	done

	exit 1
}

cleanup() {
	echo -n "Cleaning up instances of MinIO ..."
	pkill -9 minio || sudo pkill -9 minio
	rm -rf /tmp/sitea
	rm -rf /tmp/siteb
	echo "done"
}

cleanup

## 의존성으로서의 클래스

파이썬 클래스의 인스턴스를 생성하기 위해 사용하는 것과 동일한 문법을 사용한다는 걸 알 수 있습니다.

예를 들어:

```Python
class Cat:
    def __init__(self, name: str):
        self.name = name


fluffy = Cat(name="Mr Fluffy")
```

이 경우에 `fluffy`는 클래스 `Cat`의 인스턴스입니다. 그리고 우리는 `fluffy`를 만들기 위해서 `Cat`을 "호출"했습니다.

따라서, 파이썬 클래스는 **호출 가능**합니다.

그래서 **FastAPI**에서는 파이썬 클래스를 의존성으로 사용할 수 있습니다.
