I have just implemented some changes for the various factory targets of devel:languages:python. Most importantly, the openSUSE_Factory_ARM, openSUSE_Factory_PowerPC, and openSUSE_Factory_zSystems build targets have been rolled into the openSUSE_Tumbleweed build target. They are now architectures of openSUSE_Tumbleweed rather than stand-alone repositories. The existing repositories are still there. Assuming there are no problems they will be disabled on in 2 days (Sunday, April 2) and will be deleted in one week (Friday, April 7 2017).
Second, the opensuse_factory_staging build target has already been deleted. It was purely a testing repository, so nobody should have been using it to begin with.
Thank you, Todd
