failing to instantiate an inner class because of its order

[Pyenos]

class Model:
Controller()

class View:
Model()

class Controller:pass
Python interpreter complains that 'Name Error: Controller()' not defined.

Pyenos <py****@pyenos.orgwrites:

class Model:
Controller() #problem

class View:
Model()

class Controller:pass
Python interpreter complains that 'Name Error: Controller()' not defined.

Following Edward Kozlowski's advice I can suggest to myself a solution:

class Model:pass

class View:
Model() #this part is fine

class Controller:
def __init__(self):
self.Model=Model()

Controller.Model.Controller() #solution

class Controller:

Controller().Model.fuck() #actually slight problem in previous solution
Has to call in this way. I have confirmed this works.

The Model() inside View is *not* fine - you construct a Model
instance just to discard it! Besides some side effects that
constructing a Model() might have, this is useless.
If you are trying to implement a real MVC, usually the model exists
by itself even before you need the view, so usually the view
constructor gets the model as an argument.
I prefer to use lowercase attribute names: self.model = Model(), this
way there is no confusion between model (an instance) and Model (a class).

class Model:

def fuck(self):print "fuck!"

class View:
Model() #this part is fine

class Controller:
def __init__(self):
self.Model=Model()

Controller().Model.fuck() #actually slight problem in previous solution

What is even the point of the class View there since you don't use it?
