I have searched all over and haven't found the solution
for my problem yet. I am new to python, and all the time realize I
do program python in java, which is not great.
Besides being a real-life problem, I want to
solve it as elegant as I can, using it to
also learn about python (I know I could just
hack something easy for now).
That's what I want to do.
I have an Account class.
An Account instance has to get an account number.
On instance creation, I want the account number to
be generated (I don't want callers to pass
the account # to ensure uniqueness):
def __init__(self, holder):
self.__accountnumber = self.__generate_account_number()
Now, I do not know yet how the account number scheme looks like.
For now, I just want to have an incremental number; later,
when going to production, we'll need the proper one.
Furthermore, as we plan to distribute the package, we want
to allow custom account numbering schemes. Thus, customers
should be able to plug in their own AccountNumberGenerator implementation.
For now, I have a generators.py module.
I have an AccountNumberGenerator base class,
all subclasses should implement "generate".
I have an IncrementalGenerator subclass.
So for now, I need to instantiate IncrementalGenerator,
allowing for a future module to plugin their own generator.
Any suggestions on how to do this?
Thanks so much!!!!
