It's a trade off, but you can always hide those details in a utility module
or something.
# utils.py
import maya.api.OpenMaya as om2
def asSelectionList(iterable):
selectionList = om2.MSelectionList()
for each in iterable:
selectionList.add(each)
return selectionList
def asDagPaths(iterable):
selectionList = asSelectionList(iterable)
for i in xrange(selectionList.length()):
yield selectionList.getDagPath(i)
# foo.py -- usage code
import maya.api.OpenMaya as om2
import maya.cmds as cmds
import utils # utility module
for meshPath in utils.asDagPaths(cmds.ls(type='mesh')):
fnMesh = om2.MFnMesh(meshPath) # got it!
