Write a wrapper module jpwrap.py:

from jp import *
jpabs = abs
del abs

and import this as:

from jpwrap import *

My pleasure.
However, it is considered bad style to use from ... import *
outside an interactive session. Explicit is better than implicit.
This works also:

import jp
jp.abs(someArgWithSpecializedType)

When your module name is very long, use eg.:

import moduleWithLongName as lNamMod

When the dot operator gets too expensive replace
it by a local variable in the loop.

Good luck,
