Question

I have something like this:

class SomeObject:
    #code to access parents MyVar

class MyClass:
    MyVar = 3

    MyObject = SomeObject()

I need to access MyVar from inside MyObject. Is there any way I can do that?

Thank you!

Answer 1

You can store a reference to the MyClass object in the SomeObject. You can initialise the reference when you make an constructor with a MyClass Object as parameter.

class SomeObject:
    def __init__(self, reference):
         self.reference_=reference
    #code to access parents MyVar
    self.reference_.MyVar=5

class MyClass:
    MyVar = 3

    MyObject = SomeObject(self)

As unutbu stated my code was not running, therefore a more detailed example.

class SomeObject:
    def __init__(self):
         self.reference_=None

    def connect(self, reference):
        self.reference_=reference
    #code to access parents MyVar
    def call(self):
        self.reference_.MyVar=5

class MyClass:
    MyVar = 3
    MyObject = SomeObject()
    def connect(self):
        self.MyObject.connect(self)

if __name__ == '__main__':
    myclass = MyClass()
    myclass.connect()
    myclass.MyObject.call()
    print(myclass.MyVar)
