Linkage Problem and Solution: The version of Python was 2.7 and needed 2.6 so I unlink the package binary file and now works perfectly. - Thank You

Python 2.7.13 (default, Jan 5 2017, 12:39:11)

No module named yum
Used the following command to check my Python's version causing the problem. - art.s 01/16/2017

-bash-4.1$ python -v (TRUSS-LIKE)

Step1:
-bash-4.1$ ls -l /usr/bin/python
lrwxrwxrwx. 1 root root 22 Jan 16 14:47 /usr/bin/python -> /opt/splunk/bin/python

Step2:
-bash-4.1$ sudo unlink /usr/bin/python

Step3:
-bash-4.1$ sudo ln -s /usr/bin/python2.6 /usr/bin/python

Step4: Old version binary file was relinked
-bash-4.1$ python --version
Python 2.6.6

Step5:
-bash-4.1$ yum
Loaded plugins: refresh-packagekit, security, ulninfo
You need to give some command
Usage: yum [options] COMMAND

yum is built on the system DEFAULT python

Warning:
YOU CAN NOT REPLACE THAT VERSION!!!

now you can install a second,third,or fourth version in a side by side set up
the DEFAULT set up for python in the rhel/cent/sl/oracle repos

You're correct - But the version is back to its original state now 2.6
