extract plane component with python

Hi,

I'd like to extract component form planes I create with a python script - there is a lot of them, I have to make them rotate arount an other plan's axes so in order to avoid complex calculation I planed to extract axes informations, and recrate planes using new and extracted vectors.

But I can't find how to do so, I didn't find any method in the "plane" object type to do so, and when I tried to extract parameters with something like plane[0] I have an error about the non -subscritablity of "plane" object", when it's defined by tuple of tuples in documentation.

Any clues ?

Regards,
