Possible to create an object inside another object that is visible outside that objec

[MeghansUncle2]

Perhaps you mean this

class A:
    pass

class B:
    def __init__(self, spam):
        self.spam = spam

class C:
    def __init__(self, eggs):
        self.eggs = eggs

a = A() # instantiate A
b = B(a)
bb = B(a)
c = C(a)

# objects b, bb and c all share the same A instance
assert b.spam is bb.spam and b.spam is c.eggs

No, but that gave me an idea.

Is the below legal and will it expose the object created in A outside of A. Example below:

In the main program:

a = A(self) 
print(b)


Class A:
 def __init__(self, parentobject):
    parentobject.b = b() 

I appreciate your time answering this.
