python - 在Python中，如何测试解释程序是否正在运行Pyston，Jython，CPython？

我想从一个正在运行的Python程序内部进行测试，如果解释程序正在运行pyston，jython，ironpython，pypy等。

我想到的是在system.version上进行模式匹配并在imp.get_magic()上检查幻数，但这两者似乎有些虚弱和棘手。还有其他建议吗？

编辑：user2357112再次通过。

我尝试在已安装的每个Python版本上运行以下代码，这使Jython，Pyston和各种CPython有所不同。下降的地方是2.6之前的Python和CPython的anaconda变体。对于水蟒，这可能是正确的选择。

这是程序和结果。随意记下该工具可以或不可以使用的其他Python。

import platform
print(platform.python_implementation())

和shell脚本：

for v in $(pyenv versions); do # not quite right
    pyenv local $v
    echo "version is $v"
    python /tmp/foo.py
    echo "==================="
done

我得到以下输出：

===================

Traceback (most recent call last):
  File "/tmp/foo.py", line 1, in ?
    import platform
ImportError: No module named platform

最佳答案

如user2357112所述，您可以检查platform.python_implementation() == "Pyston"，如source中所示。
