installing python 2.7.11 on CentOS7 which already has python 2.7.5 is not working

Question

CentOS7 has python 2.7.5 by default.

$ which python
/usr/bin/python
$ python --version
Python 2.7.5

But I needed to use python 2.7.11.
So I installed that version from source.

$ wget https://www.python.org/ftp/python/2.7.11/Python-2.7.11.tgz
$ tar xf Python-2.7.11.tgz
$ cd Python-2.7.11

$ ./configure --prefix=/usr/local --enable-shared
$ make
$ sudo make install

Output of which command have changed.
But python version is still 2.7.5.

$ which python
/usr/local/bin/python
$ python --version
Python 2.7.5

So I want to know why this happened and how to fix this situation.
