You might want to: - find the package objects that match the depstrings - iterate those packages using yum.YumBase.findDeps() (this, looking at it now, is a stupid method and should take package objects, not userstrings) - that returns a dict, iterate that for each print each output to see how this works just run: yum deplist somepkgname -sv
