DNF can execute using either Python 3 or 2.

It is due to Fedora was going to transfer to Python 3 which specified that YUM would not survive this modification.

YUM rewrite named DNF substituted YUM as a default package manager in the 22 version of Fedora.

Graphical user interface-based wrappers like YUM Extender are also available and have been accepted for Fedora Linux until the 22 version.

YUM is worked as libraries with the Python programming language using a small collection of programs that offer a command-line interface.

YUM relies on RPM under the hood which is a packaging standard for software digital distribution which automatically applies digital signatures and hashes for verifying the integrity and authorship of said software, unlike a few app stores which provide the same function neither RPM nor YUM offer built-in support for essential restrictions on package copying by end-users.

YUM implements software repositories (set of packages) that can be locally used or on a network connection similar to the Advanced Package Tool from Debian.

YUM permits automatic updates and package dependency management over RPM-based distros. Many other tools offer GUI to YUM functionality because YUM contains a command-line interface. YUM ( Yellowdog Updater Modified) is an open-source and free command-line package management utility for systems executing the Linux OS with the help of the RPM package manager.
