 The line that's failing will be this one:

from rpmUtils import RpmUtilsError

...so you could see if/who that also fails from python. But this
implies that the install of yum itself is broken. You can try:

 rpm -q yum
 rpm -V yum
 rpm -Va --nofiles --nomd5

...or just force a reinstall of the yum package with rpm and see if
that helps (at which point you can run package-cleanup and
yum-complete-transaction etc. to see if they find anything).
