Hi,
I'd like to be able to access an attribute of a particular Python
object as fast as possible from some C code.
I wondered if using __slots__ to store the attribute would allow me to
do this in a faster way.
The reason I'd like to do this is because I need to access the
attribute inside a loop within some C code, and I find that the
attribute lookup using the 'PyObject_GetAttrString' call is far slower
than any of the subsequent calculations I perform in C.
That's correct. You can use slots to increase the performance but it
doesn't work like you think. If you need it *really* fast than write a C
Extension, store the data in a C struct and access the data via PyMemberDef.
