What does 'which python' return?  As Joseph said, hopefully you didn't
overwrite /usr/bin/python with Python 3.5.  If you did, you're hosed.
You'll probably have to reinstall.  Python 2.7 is required by just about
everything on CentOS 7.

If you want to use Python 3.4, install it via Software Collections
Library.  https://www.softwarecollections.org/en/

To use SCL, you'll need a working yum, though, so after you reinstall
give it a try.
