在另一类人种内确定一个等级,并采用母体方法
原标题:Defining a class within another class and calling a parent method

我对这一类有c类定义和一些内层定义:

class DoXJob():
    def __init__(self, param1, param2):
        <choose an inner class to use> 

    def DoIt(self):
        pass

    def Finalize(self):
        <do finalization>

    class DoXInSomeWay():
        def __init__(self):
            ....
            ....
        def DoIt(self):
            ...

    class DoXInSomeOtherWay():
        def __init__(self):
            ....
            ....
        def DoIt(self):
            ...

逻辑简单,即有一些内部类别定义来处理工作,而i打上DoXJob,其中有一些参数,然后决定采用哪些内部类别,并以选定的内部类别方法为准<代码>DoXJob.DoIt(DoXInSome OtherWay.DoDoXInWay.Dot)。

obj = DoXJob(param1, param2)
obj.DoIt()

所有这一切都是罚款,如从<代码>上打字。 DoXInSome OtherWay.DoIt或DoXInWay.DoIt。 但我不知道如何处理这一问题,这是否正确。 或者作为<代码>DoXJob的最好办法。 采用的方法如下:

obj = DoXJob(param1, param2)
obj.DoIt()
obj.Finalize()
最佳回答

Unfortunately, python doesn t seem to have a way to refer to the enclosing instance.

相反,在您的外在_init__上 如果你选择哪类内子使用,并假定可以当场使用,那么你就必须将外部物体的代码<>自行作为内班子的参数。

Edit: Picking up the theme of a redesign - if you can simply call the DoIt method, then wait for its return, then you can call Finalize in the same place (the caller, that is), thus avoiding the need for the inner to call the outer.
