PyPy is Powerful
----------------

There is another Python interpreter, besides CPython.
It is PyPy.
PyPy is Python made with Python.

How does it work?
Well, PyPy uses RPython, which is an extension of CPython 2.7 that compiles.

What is the difference?
Compared to CPython, PyPy has some small differences, so you should test your software with PyPy for portability.

The only downside is that C code compiled for Python has to be recompiled for PyPy.
Tools like numpy won't work in PyPy either.

Otherwise, it's a good alternative Python interpreter.
