import - confusion about importing modules in python -

i read @ to the lowest degree 2 ways import .py modules in python. suppose, have directory structure:

/foo/bar/mymodule/a.py /foo/bar/b.py

and have /foo/bar in pythonpath, , have def a123(): in a.py , def b123(): in b.py respectively.

if understand can do..

from mymodule import (suppose have __init__.py in directory) b import *

in order phone call a123() , b123().

what pros , cons of each of these 2 ways of declaring modules in python, , when should utilize 1 not other?

thanks , regards.

if have module code in 1 file, set top level directory. if have several files, create package.

python import
