  1. PyPy is a fast, compliant alternative implementation of the Python language
  2. (equivalent to CPython 2.7.1). It has several advantages and distinct
  3. features:
  4. Speed: thanks to its Just-in-Time compiler, Python programs often run
  5. faster on PyPy.
  6. Memory usage: large, memory-hungry Python programs might end up taking
  7. less space than they do in CPython.
  8. Compatibility: PyPy is highly compatible with existing python code. It
  9. supports ctypes and can run popular python libraries like twisted
  10. and django.
  11. Sandboxing: PyPy provides the ability to run untrusted code in a fully
  12. secure way.
  13. Stackless: PyPy can be configured to run in stackless mode, providing
  14. micro-threads for massive concurrency.
