Python/Class/Loop/Recompute/ExpireSolution

Hello!

I am working on a project involving Object-Oriented Programming with IronPython, and then actuating them in Grasshopper to obtain "physical" Rhino geometries as results. 

Component A, outputs an instance of a class type, which I refer to as Class Instance A for this discussion post.

Component B, has a for-loop, through which it does a few things, and makes "n" number of variations (in this case, just 3) of Class Instance A. Simplified/generalized structure of Component B is as follows:

a=[]

for i in range (n):

.....variation = DoSomething (StartShape)

.....a.append(variation)

.....for obj in ghenv.Component.OnPingDocument().Objects:

..........if obj.Name == "MakeAssembly":
...............obj.ExpireSolution(False)

I am not sure if I am using the ExpireSolution method correctly here. I also have found this (Grasshopper.Instances.ActiveCanvas.Document.NewSolution(False)) from some other discussions, but it doesn't seem to solve this problem. Or maybe I have the placement of ExpireSolution or NewSolution wrong. Upon pressing F6 then F5, Component B keeps updating Class Instance A, instead of "resetting" it to its original condition. For-loop in Component B must have the original Class Instance A every time, in order for it to spit out variations. I need to find a way to expire the solution for Component A only, at the end of each For-loop. Eventually, I need it to loop 100+ times, so manually pressing F5 is not really an option... Below is an image of what should happen:

What is the best way to tackle this problem (in either Grasshopper-Python or IronPython), so that the same original Class Instance A is fed in every time the loop is run in Component B?

Thank you!
