Hi! I want to be able to create elements, and want their parents to be elements, so I've been reading this page: http://www.sagemath.org/doc/reference....

The example shows Cython commands it seems (cdef v def).... Why? Couldn't I just do this in Python?

Excerpt from page cited above.

Elements typically define a method _new_c, e.g.,

cdef _new_c(self, defining data): cdef FreeModuleElement_generic_dense x x = PY_NEW(FreeModuleElement_generic_dense) x._parent = self._parent x._entries = v

Elements can be implemented in plain Python and in Cython. Often, Cython is used for speed but you don't have to.

You should have a look at the worksheet on http://trac.sagemath.org/11490

Wonderful. I had no idea that there were these educational worksheets about Sage development. Is there a general repository for them? (I've posted this as a different question). Thanks!
