A DNF-ben a Python API t\u00e1mogat\u00e1sa megmarad, de a Python nyelven \u00edrt \u00fczleti logika \u00e1tkonvert\u00e1l\u00e1sra ker\u00fcl a libdnf (C++) k\u00f6nyvt\u00e1rba, ami biztos\u00edtja a csomagkezel\u0151 m\u0171k\u00f6d\u00e9s\u00e9nek egyez\u0151s\u00e9g\u00e9t a disztrib\u00faci\u00f3ban.
