[Python-Dev] import problems (original) (raw)

The variant proposed by Hrvoje Niksic:

>>> import(modname) >>> mod = sys.modules[modname] looks more appealing, but comes with the drawback that sys has to be imported for that purpose only. That is not a real drawback, as "sys" will certainly be present in the system, so the "importing" boils down to a dict lookup and a variable assignment.

I meant that you have to

import sys

only to access sys.modules (i.e. importing sys may not be necessary otherwise).

Compare

mod = import(modname, submodule=True)

with

import sys import(modname) mod = sys.modules[modname]
