This script will build python-2.7.x on a centos 6.x box. Tested on vagrant.

%description
Python is an interpreted, interactive, object-oriented programming
language.  It incorporates modules, exceptions, dynamic typing, very high
level dynamic data types, and classes. Python combines remarkable power
with very clear syntax. It has interfaces to many system calls and
libraries, as well as to various window systems, and is extensible in C or
C++. It is also usable as an extension language for applications that need
a programmable interface.  Finally, Python is portable: it runs on many
brands of UNIX, on PCs under Windows, MS-DOS, and OS/2, and on the
Mac.

%package devel
Summary: The libraries and header files needed for Python extension development.
Requires: %{name} = %{version}-%{release}
Group: Development/Libraries

%description devel
The Python programming language's interpreter can be extended with
dynamically loaded extensions and can be embedded in other programs.
This package contains the header files and libraries needed to do
these types of tasks.

Install python-devel if you want to develop Python extensions.  The
python package will also need to be installed.  You'll probably also
want to install the python-docs package, which contains Python
documentation.
