How to access inner class from outer class in python

May 16, 2022

If possible, not examples with print. But more like with real arguments

Really basic example :

class A:
    def __init__(self):
        pass
    def create_project(self,argA):
        
        newA = call createFromA(argA)
        
        return newA      
        
    class Constructor:
        def __init__(self):
            pass
        def modifA(Abis):
            Abis = Abis + Abis
            return Abis
        def createFromA(self,argA):
            A = 2*argA
            A = modifA(A)
            return A
        
        
cons = A()
cons.create_project(2)

Can someone shed me some light on how I can call createFrom into the outer class

>Solution :

createFromA needs to be a staticmethod as it does not operate on instances of the class Constructor

class A:
    def __init__(self):
        pass
    def create_project(self,argA):
        
        newA = self.Constructor.createFromA(argA)
        
        return newA      
        
    class Constructor:
        def __init__(self):
            pass
        @staticmethod
        def createFromA(argA):
            A = 2*argA
            return A
        
        
cons = A()
cons.create_project(2)
