Python can be downloaded from http://python.org

For unix platforms download the .tgx file , extract the files and go to the main directory. Build Python by performing the following:

1. ./configure
2. make
3.  make install

Python is usually installed in a standard location so you can find it rather easily. It has become quite common place for systems today to have multiple versions of Python installed. While it is easy to find the binary executable, you also have to deal with where the libraries are installed.
