问Python3.x可以强制一个方法param是一个特定的类实例/对象吗？(ala PHP)

EN

public class Foo()
{
    public function __construct($qux, ...)
    {
        $this->qux = qux;
        ...
    }
}

public class Bar() 
{
    // "Type Hinting" done here enforcing 
    // that $baz is an instance of Foo
    public function __construct(Foo $baz, ...)
    {
        $this->baz = $baz;
        ...
    }
}

class Foo(object):
    def __init__(self, qux=None, ...):
        self.qux = qux
        ...


class Bar(object):
    def __init__(self, baz=None, ...):
        # "Type Hinting" done here as `assert`, and
        # requires catch of AssertionError elsewhere
        assert isinstance(baz, Foo)

        self.baz = baz
        ...
