'Python' is a language with multiple versions. Python2.x is the older 
series, but still in use Python3.x is the newer series of versions. 
Pythonx.y is a particular version.

CPython is the main *implementation* of Python. It comes with a standard 
library of modules that you can import. Other people provide other 
modules and packages of modules that you can import.

Numpy is a package for numerical computation with multi-dimensional 
arrays. Scipy is a package for scientific computation that uses numpy.

There are several packages for adding a graphical user interface to a 
program. WxPython is one of those. It is the Python wrapper for the 
wxwidgets library. It is not a 'python' in itself.
