我怎么知道我正在使用哪个python实现？

Question

Python有一些不同的实现：CPython，Jython，PyPy等。我想以编程方式确定运行我的代码的实现。我怎么能这样做？

具体来说，为我编写一个名为get_implementation_name()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..."

Answer 1

In [50]: import platform    
In [52]: platform.python_implementation()
Out[52]: 'CPython'

Answer 2

platform

怎么样？

它给你

platform.python_implementation()
