Is there a way to access outer class in the nested class in python?

just a very simple thing, is there a way to access outer class from the inner class definition, like this:

class Model:
  class Options:
    model = Model   <-- error!

I nest Options inside Model because semantically these Options 开发者_如何转开发exist only in the scope of model, so it seems appropriate.

Thanks, Alex

I am not sure this is exactly what you wanted but try:

class Model:
    class Option:
        @property
        def model(self): return Model

Well, you can at least instantiate the outer class in a method of the inner class:

class Model:
    class Options:
        def __init__(self):
            model = Model()

Try:

class Model:
    pass

class Options:
    model = Model

Another solution is to do the assignment after the class definition.

class Model:
  class Options:
    pass

Model.Options.model = Model
