What exactly is an "Implementation of Python" ?

2008-11-07 Thread webtourist
Warning: New learner here

Not sure what the term means "implementation of Python".
So what exactly does it mean *"implementation of Python"* like
cpython, Jython, IronPython ?

In terms of IronPython --- does it mean a Python programmer can
write .Net app in Python ?

Thanks


examples and ANALOGIES if possible, very welcomed.

Can you tell us what book it is ?

If this is just your first and only book so far,
IMO, I think you can look at another one or two
I recently re-discovered Steven Lott's excellent free book "Building
Skills in Python" (http://homepage.mac.com/s_lott/books/
python.html#book-python)
and then there is the popular "Think Python" by Allen Downey

New bie Question:
in "Zen of Python" - what exactly does the last one mean ? -
Namespaces are one honking great idea -- let's do more of those!

I mean why the emphasis ? Is it like saying "put modules into
packages" in other programming paradigm s ?

thanks
