The CLI script files have additional pylint issues that were not noticed before. The violations include using dict.keys() without directly iterating of the result, inconsistent return statements and set([]) instead of set literals. * dict-keys-not-iterating * inconsistent-return-statements * onsider-using-set-comprehensio See: https://pagure.io/freeipa/issue/7772 Signed-off-by: Christian Heimes <cheimes@redhat.com> Reviewed-By: Thomas Woerner <twoerner@redhat.com>
