不多说，直接下上我的代码

首先，在windows的gvim里，现在发现通过set pythonthreedll=, set pythonhome=不能设置pythonthreedll和pythonhome，放狗后建议下面的设置方法

let &pythonthreedll='C:\Anaconda3\python37.dll'

let &pythonthreehome='C:\Anaconda3'

然后检测系统python版本、位置，返回的python版本是一个小数，如3.73, 2.717。

有些vim插件如defx, denite, deoplete是需要python3.6.1+， 那在vim配置里只要 g:python_version >3.6即可。
