Python 第三方库 cp27、cp35 等文件名的含义

What does version name ‘cp27’ or ‘cp35’ mean in Python?

如对于 gensim-0.12.4-cp27-none-win_amd64.whl文件名而言，将其文件名拆分的话，含义分别是：

• 0.12.4 - package version, they may be using semantic versioning
• cp27 - this package is for CPython. IronPython, Jython, or PyPy will probably be unhappy.
  
  • CPython version 2.7.
• none - no feature of this package depends on the python Application Binary Interface, or ABI
• win_amd64 - this has been compiled for 64-bit Windows. That means that it probably has some code written in C/C++
• .whl - that means this is a wheel distribution. Which is handy, because it means if you’re running CPython 2.7 64-bit on Windows, and assuming you have pip installed, all you have to do to get this package is run: py -2.7 -m pip install –use-wheel gensim (assuming that it’s available on pypi, of course). You may need to py -2.7 -m pip install wheel first. But other than that, that should be all it takes.
