如何从 SQLAlchemy 映射对象中发现表属性

I have a class mapped with a table, in my case in a declarative way, and I want to "discover" table properties, columns, names, relations, from this class:

engine = create_engine('sqlite:///' + databasePath, echo=True)

# setting up root class for declarative declaration
Base = declarative_base(bind=engine)

class Ship(Base):
    __tablename__ = 'ships'

    id = Column(Integer, primary_key=True)
    name = Column(String(255))

    def __init__(self, name):
            self.name = name

    def __repr__(self):
            return "<Ship('%s')>" % (self.name)

所以现在我的目标是从Ship"类从另一段代码中获取表列及其属性.我想我可以使用检测来处理它，但是 SQLAlchemy API 是否提供了任何方法?
