```Python
something()
```

또는

```Python
something(some_argument, some_keyword_argument="foo")
```

그것은 "호출 가능(callable)"입니다.

## 의존성으로서의 클래스 { #classes-as-dependencies_1 }

파이썬 클래스의 인스턴스를 만들 때도 같은 문법을 사용한다는 것을 알 수 있을 겁니다.

예를 들어:

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


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

이 경우 `fluffy`는 클래스 `Cat`의 인스턴스입니다.

```Python
something()
```

または

```Python
something(some_argument, some_keyword_argument="foo")
```

これを「呼び出し可能」なものと呼びます。

## 依存関係としてのクラス { #classes-as-dependencies_1 }

Pythonのクラスのインスタンスを作成する際に、同じ構文を使用していることに気づくかもしれません。

例えば:

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


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

この場合、`fluffy`は`Cat`クラスのインスタンスです。

```Python
something()
```

或者

```Python
something(some_argument, some_keyword_argument="foo")
```

这就是 "可调用对象"。

## 类作为依赖项 { #classes-as-dependencies_1 }

你可能会注意到，要创建一个 Python 类的实例，你可以使用相同的语法。

举个例子:

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


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

在这个例子中, `fluffy` 是一个 `Cat` 类的实例。

    Our workaround is to tell GWT that util.concurrent and all other packages
    have prod supersource, even if they have none. GWT is happy to ignore us
    when we specify a nonexistent path.

    (I hope that this workaround does not cause its own problems in the future.)

## Una *instance* "callable" { #a-callable-instance }

En Python hay una forma de hacer que una instance de una clase sea un "callable".

No la clase en sí (que ya es un callable), sino una instance de esa clase.

Para hacer eso, declaramos un método `__call__`:

{* ../../docs_src/dependencies/tutorial011_an_py310.py hl[12] *}

      public boolean isExpectedType(Throwable cause) {
        return cause instanceof NullPointerException
            || cause instanceof IllegalArgumentException
            || cause instanceof UnsupportedOperationException;
      }
    };

    abstract boolean isExpectedType(Throwable cause);
  }

  private static boolean annotatedTypeExists() {
    try {
      Class.forName("java.lang.reflect.AnnotatedType");
