I am reading Russian newsgroups

Thanks for your answer, but I still don't understand: 
if Python reserves some memory via malloc() for that string 
and assigns it to the pointer str, who will free that memory?
Py__Finalize()? And if Python does not allocate any memory
and uses some static storage, why won't it get overwritten
by subsequent calls of PyArg_ParseTuple()?
