Are you sure you want an STL container? Since the primary operator here is Python, the extra benefits from the STL container over plain C arrays isn't as evident. Pyrex is a good way to write the interface between your C++ code and the Python code - it handles the refcounting and boilerplate for you - and perhaps for writing the algorithms as well, depending on how complicated and performance sensitive they are. Also, using numeric/Numarray can be a very big win. It can potentially save you a fair amount of marshalling overhead. -- http://mail.python.org/mailman/listinfo/python-list
