How to specify which python to use when writing vim script in python

Question

I started to learn how to write vim script in python.

I come across of this tutorial

https://dzone.com/articles/how-write-vim-plugins-python

and my first vim script looks like the following

function! Reddit()

python << EOF
import sys
print sys.executable
print "hello Reddit"
EOF

endfunction

as you can see, the print sys.executable prints out the python on the system path.

As I use pyenv a lot, how can I set vim to recognize my python according to my working environment?

If you don't mind using Neovim instead of vim, you would be able to select which Python interpreter to use via:

let g:python_host_prog = '/path/to/your/interpreter/python'
let g:python3_host_prog = '/path/to/your/interpreter/python3'
