I'm really enjoying python in my Netbeans IDE. I would like to know extensive difference between these version of Python: Cpython, Jython, Iron python, pypy .....etc (You can add it). What is the main difference? Why all these versions? What are end products of all these versions? (.exe, .jar, etc). Why should I use one of them? Can I have all of them? Why?
You can add as many question as you can as well as answer as much as you can.
