python not working on RHEL6

[Madushan Chathuranga]

Hi,

when I type python2.6 terminal opens for python. So no issue on that. but when I type python2.7, python or any yum command It gives the error,
python: error while loading shared libraries: libpython2.7.so.1.0: cannot open shared object file: No such file or directory 

Thanks
