Exactly. The data store knows a lot more than the client (your
program) will ever know.
The correct answer is to do nothing. Use your data store to generate
the IDs for you. The implementations
Thanks for all replies.
I need to practice much more pythonese
In fact I don't think to understand all
of your suggestions, so I'll need to
go through them and decide what approach I am going
to take.
Thanks a lot!

You'd write a di
What Paul was trying to elaborate on is that have your customers or whomever
will use this implement their own generator protocol to generate whatever
number format they need. Paul just gave you an example with
itertools.count(), where it is an infinite generator that yields count+1
every time.

Thanks Paul,
Ugh, just forget everything you ever knew about java. Do some Zen
exercises to erase your mind. Then read a Python tutorial as if

Yeah, surely right, but easier said than done...
I'm working on it.
Taking your example.

Stefan, thanks first of all
Use a global variable in the module.
I have an account_number_generator variable in the module,
I got that hint from searching the web.
But where my stubborn java mind doesn't release me:
what does the variable contain? Do I create the actual

Hi
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 co
