I'm not a vim user and I only got to work something similar with Python 2.
I put
print "hello"
into mylib.py
and saw when it was printed with the following script:
function! Foo()
python << HERE
import sys
sys.path.append(".")
import mylib
HERE
endfunction
function! Bar()
python << HERE
import mylib
HERE
endfunction
:so vimscript.txt
:call Foo()
--> hello
:call Bar()
--> (nothing)
Conclusion: both functions share the same Python interpreter.
With a function containing
import os
print os.getpid()
you can also see that the Python interpreter runs in the same process as
vim.
