There is a package named rpm-python which provides binding to RPM tool.
I don't know how the RPM output change from distro to distro so probably
it is better to use the python binding.
This output *shouldn't* change from distro to distro because --qf
"%{version}" means I'm querying only the version of that package. In
practice, for --qf (queryformat) rpm calls printf so we could change the
output in our own way:
# rpm -q --qf "name:\t%{name}\nversion:\t%{version}\n" -f /etc/os-release
name: fedora-release
version: 21
# rpm -q --qf "name:\t%{name}\nversion:\t%{version}\n" -f /etc/os-release
name: openSUSE-release
version: 13.2
But I'm checking how can I do it using the rpm binding.

You can use os.uname()[4] to get the arch
I cannot use os.uname() here because I need the basearch, not the arch.
check out the difference:
# uname -i
i383

> os.uname()[4]
