Some don't realize that one very powerful use for the .format style of working is that it makes localization much more straightforward. With the curly brace approach, one can translate the format string into another language, and if the parameters have to be substituted in another order, it's all in one place. Twenty years ago, I implemented such a thing for our product (C++), for just that reason. I'm sure that by now, the libraries exist somewhere in the C++ stdlibs, or at least in Boost. -- DaveA -- http://mail.python.org/mailman/listinfo/python-list
