It wasn't clear to me from your (OP's) post whether your difficulty
was in using Python within Vim, which I know nothing about, or in
using a list in a complete (as in command completion) function.

If you just want a completion function that returns a list of files
containing "Module", this should work.

function! Foo(ArgLead, CmdLine, CursorPos)
return system("grep -iRl Module .")
endfunction

Here's a command that uses that function.

command! -nargs=1 -complete=custom,Foo Bar edit <args>
