Thanks for the patch. However, perhaps a more general solution would be to use the Python locale module to format numbers according to different locales. And expose a kwarg select between the user's preferred locale, the current U.S. English-centric defaults as they are now, or an arbitrary locale using an ISO language code. That seems like it could be a better long-term solution, since there are different number formats all over, not just in Germany.
All that said, internationalization is hard -- especially for us sheltered people in the U.S. where the defaults are most often correct. I may be missing an important detail here.
