///////////////


    Download (there may be newer releases on Python.org):

    $ wget https://www.python.org/ftp/python/3.4.3/Python-3.4.3.tar.xz

    Unzip

    $ tar xf Python-3.* 
    $ cd Python-3.*

    Prepare compilation

    $ ./configure

    Build

    $ make

    Install

    $ make install

    OR if you don't want to overwrite the python executable (safer, at least on some distros yum needs python to be 2.x, such as for RHEL6) - you can install python3.* as a concurrent instance to the system default with an altinstall:
    $ make altinstall
Python-2.7
#!/usr/bin/pytho/usr/local/bin/python2.6
find / -type f -executable -name 'python2*'
