Python 有几个不同的实现：CPython、Jython、PyPy 等。我想以编程方式确定我的代码在哪个实现上运行。我怎样才能做到这一点？

具体来说，写一个get_implementation_name()为我调用的函数：

impl_name = get_implementation_name()
if impl_name == "CPython":
  print "I can abuse CPython implementation details. (I'm a bad, bad man.)"
elif impl_name == "PyPy":
  print "Can't count on reference-counting garbage collection here..."
else:
  print "I better be careful..."
