Solution

You could try compiling it from sources, in root :

yum -y install python-devel openssl openssl-devel gcc sqlite-devel

wget http://www.python.org/ftp/python/2.7.5/Python-2.7.5.tar.bz2
tar -xvjf Python-2.7.5.tar.bz2
cd Python-2.7.5
./configure --prefix=/usr/local/python2.7 --with-threads --enable-shared
make
make install altinstall

ln -s /usr/local/python2.7/lib/libpython2.7.so /usr/lib
ln -s /usr/local/python2.7/lib/libpython2.7.so.1.0 /usr/lib
ln -s /usr/local/python2.7/bin/python2.7 /usr/local/bin
/sbin/ldconfig -v

Then test getting correct python /usr/local/python2.7/bin/python2.7 -V

And, as normal user :

echo "alias python='/usr/local/python2.7/bin/python2.7'" >> ~/.bashrc
source ~/.bashrc
python -V    

Good luck :)

Please, don't. Compile stuff yourself and replace system binaries is not recommended at all, unless you fully understand what your're doing.

Recompile python source code and install did not help, the problem is solved until soft links are created according to your solution. Thanks.
