Almost.  Your version above has the argument to get_python_lib reversed;
with no arguments it returns the arch-independent path ("sitelib"), and
with 1 the arch-dependent path ("sitearch").  Additionally, your version
uses "python" instead of "%{__python}" which takes away a bit of the
flexibility.

Here's what's in fedora-rpmdevtools' spectemplate-python.spec:

%{!?python_sitelib: %define python_sitelib %(%{__python} -c "from distutils.sysconfig import get_python_lib; print get_python_lib()")}
%{!?python_sitearch: %define python_sitearch %(%{__python} -c "from distutils.sysconfig import get_python_lib; print get_python_lib(1)")}
