Class optimization at runtime

Kind of hard to tell what you are trying to accomplish
but I'll try. Define the class with no if/else statements.
They only get parsed once. It is the "class instance"
creations that may get created millions of times. They
will be inside your logical structure.
class Foo:
def __init__(self):
# do stuff
class Bar:
def __init__(self):
# do stuff
if option: x=Foo()
else: x=Bar()
HTH,
