I am new to Python and have to create an import library in C that uses

matrices.

These matrices can be one-dimensional (vectors) or two-dimensional. If I

look in the ActivePython 2.4 documentation at data structures, then I see at

least 2 posibilities to represent them: Lists and Tuples.

The documention doesn't give me much information on what the best choice is

for the data type to provide/return these matrices.

So my question is, should I use lists or tuples to represent my matrices in

and why?

Thanks for any reaction.
