What's the difference?

Question

I want to know what is the main difference between python, python3 and cpython.

Answer 1

There are plenty of python implementations
* when people say python they are referring to Cpython implementation (the technical name) it's the commun one; and it has two main versions 2.7 and 3.6 when you see python3 people are referring to Cpython version 3

The Cpython it's a way to differentiate of other mayor's implementation like:

* jyhon(interpreter of python for Java) ,
* ironpython(python for Net) ,
* pypy( python with steroids, a lot faster and better memory use,micro-threads for massive concurrency. but a smaller community )

the implementation are different But the language is the same(with small differences) .

Answer 2

you can google also jython
