Python 2.6：类内的类？

我认为您在混淆对象和类。一个类中的一个类如下所示：

class Foo(object):    class Bar(object):        pass>>> foo = Foo()>>> bar = Foo.Bar()

但是在我看来，这不是您想要的。也许您遵循的是简单的收容层次结构：

class Player(object):    def __init__(self, ... airplanes ...) # airplanes is a list of Airplane objects        ...        self.airplanes = airplanes        ...class Airplane(object):    def __init__(self, ... flights ...) # flights is a list of Flight objects        ...        self.flights = flights        ...class Flight(object):    def __init__(self, ... duration ...)        ...        self.duration = duration        ...

然后，您可以按照以下方式构建和使用对象：

player = Player(...[    Airplane(... [        Flight(...duration=10...),        Flight(...duration=15...),        ] ... ),    Airplane(...[        Flight(...duration=20...),        Flight(...duration=11...),        Flight(...duration=25...),        ]...),    ])player.airplanes[5].flights[6].duration = 5
