Of course you could make a module vvv.py with lots of import statements
import aaa
import bbb
...
import zzz
but then all submodules are imported eagerly with
import vvv
And then there's the hack
import sys
class Importer(object):
def __getattr__(self, name):
module = __import__(name) # you can do anything here
setattr(self, name, module)
return module
sys.modules["vvv"] = Importer()
