When importing a module from a subpackage, it's sometimes convenient
to refer to it throughout the code with a one-part name rather than
two. I'm going to use 'os.path' for the examples, but my actual
use-case is a custom package where the package name is, in the
application, quite superfluous.
Throughout the code, I want to refer to "path.split()",
"path.isfile()", etc, without the "os." in front of them. I could do
either of these:
import os.path as path
from os import path
Which one would you recommend? Does it depend on context?
One argument not yet brought up by anyone else:
if you ever wanted to make the module part of your own package and turn
the import into a relative one, only the second, but not the first form
lets you replace the package name with . :
from . import path (while import .path is a SyntaxError, so you'd need a
slightly more complicated rewrite).
