delete yum accidentally

[sumits7y]

I was trying to uninstall python2.7 but accidentally uninstalled yum to reinstall yum I downloaded yum rpm package but not able to install it
when I install I get

package yum-3.4.3-161.el7.centos.noarch is already installed

and when i run any yum command i get

bash: yum: command not found...

You can't "accidentally" remove yum. If you run yum remove yum it will tell you to go away. If you use rpm -e then it will tell you that it can't because there are dependencies. The only way to do it is to use rpm -e --force or --nodeps and at that point it's akin to buying a shotgun and pointing it at your own foot.

You can try rpm --reinstall /path/to/yum-3.4.3-161.el7.centos.noarch and see if that works.
