简化代码:作为简易集装箱的舱位
原标题:Simplifying code: classes as simple containers in Python

我正试图写一个职能<代码>drag,可称之为drag(目标1 )to(目标2 )。 下面的代码按我的愿望运作,但似乎使用了<代码>> /代码>。 仅仅作为集装箱可能没有必要:

def drag(source):
    class Container:
        def to(self, target):
            print  Dragging   + source +   to   + target

    return Container()

Can the above code be simplified?

最佳回答

我认为,你可以使用一个具有源头的类别,在“代码”到<>/代码”时,可以使用一个目标,并打印信息。 您可称之为<代码>drag:

class drag:
    def __init__(self, source):
        self.source = source
    def to(self, target):
        print  Dragging   + self.source +   to   + target

或您可使用<条码> 所载明码类别,且有<条码>drag<>。 简单地说,是一种叫作初始者的职能:

class Container:
    def __init__(self, source):
        self.source = source
    def to(self, target):
        print  Dragging   + self.source +   to   + target

def drag(source):
    return Container(source)

我将指出,这一职能实际上没有做任何事情,试图像这样写一个有用的类别/职能,就会使你的守则不明确,而不会增加任何内容。
