Dynamically Importing Python Modules

If you ever need to dynamically import Python modules this short function will do the trick. The modules will be imported into the importing modules main. 

def importMods(path, fromList, asList=None):
    modules = __import__(path, globals(), locals(), fromList, -1)
    if not asList: asList = fromList
    if len(asList) != len(fromList): raise ValueError('asList != fromList')

    for asMod, mod in zip(asList, fromList):
        exec "importMods.func_globals['%s'] = modules.%s" % (asMod, mod)
