I am a newbie in python. Right now I am working on this messaging app and I
would like to pass data from one protocol to another. I have been referencing
to other answers provided in other similar questions by trying to add a
variable storing the data from one factory then initiate another factory and
write the data to it. Unfortunately it is only writing back to itself now
instead of writing to another factory, and I cannot figure out why. If anyone
can provide any sort of help I will really appreciate it as I have been stuck
in this point for quite a while.
