It is worth mentioning that the above solution will only work outside of a function.

This will not give the desired result:

function! MyFunction()
let s:current_file=expand(':p:h')
echom s:current_file
endfunction

But this will:

let s:current_file=expand('')
function! MyFunction()
echom s:current_file
endfunction

Here's a full solution to OP's original question:

let s:path = expand(':p:h')

function! MyPythonFunction()
import sys
import os
script_path = vim.eval('s:path')

lib_path = os.path.join(script_path, '.') 
sys.path.insert(0, lib_path)                                       

import vim
import plugin_helpers
plugin_helpers.do_some_cool_stuff_here()
vim.command("badd %(result)s" % {'result':plugin_helpers.get_result()})

EOF
endfunction
