Python's implementation classification

The current popular Python implementation includes cpython,jython,ironpython,stackless,pypy,cython,shed skins.

CPython

CPython is the standard implementation of Python, the entire implementation has been written in ANSI C, is currently the most widely used Python implementation, Linux and Max OS x installed on most of the CPython.

Jython

Jython is Phthon for Java, primarily for Python to invoke Java applications, as if CPython could make Python call C and C + +. Jython translates Python's source code into Java bytecode, then Java bytecode is then executed by the Java virtual machine

IronPython

IronPython is python for net, primarily for Python to call Net and C #.

Stackless

Stackless is python for concurrency, mainly to optimize Python's concurrency capabilities.

PyPy

PyPy is python for Speed,pypy primarily uses instant compilation (jit,just-in-time) to improve Python execution speed

Cython

Cython strictly speaking is not a Python implementation, because Cython does not strictly implement the Python language, it is actually a python and C mixed programming technology, allowing the C language in Python to call functions, declare variables and so on

Shed Skin

Shed skin strictly speaking is not a Python implementation, because it takes Python as a static language, need to compile, and then run, and in fact, the real Python should be interpreted language, She skin will be python directly compiled into C + + machine code, Then run directly
