Huh?  I must be missing something here.  Isn't this what you use a 
variable for:

     sharedFloat = 123

and later

   sharedFloat = 99

The variable sharedFloat could exit as a global (in some module) or as a 
instance variable in some shared object or anywhere else you want to 
store it.

As a module attribute:

     import Shared
     Shared.sharedFloat = 123

Or as a class attribute:

     class Shared:
       sharedFloat = 0

     Shared.sharedFloat = 123

or as an instance attribute:

   class Shared:
     def __init__(self):
         self.sharedFloat = 0

   sharedObject = Shared()
   sharedObject.sharedFloat = 123
