Is there any reason not to use a standard factory pattern for this? It 
is the normal approach.


# Factory.py

import class1, class2, class3

def Factory(class_type):
     if class_type='class1':
         return class1()
     elif class_type='class2':
         return class2()
     elif class_type='class2':
         return class3()



# using the factory
from Factory import Factory
myObject = Factory(class2)
