import("distutils.core", level=0) <module 'distutils' from_ _'/home/antoine/py3k/_svn_/Lib/distutils/_init_.py'> sys.modules["distutils.core"] <module 'distutils.core' from_ _'/home/antoine/py3k/_svn_/Lib/distutils/core.py'> That's right, but I believe the recommended way to achieve that behavior is to supply a dummy fromlist: import("distutils.core", fromlist=["dummy"], level=0) <module 'distutils.core' from_ _'/Users/sasha/Work/python-svn/py3k/Lib/distutils/core.py'> No! That's not recommended and a complete hack. The "dance" or importlib.importmodule is preferred.

A complete hack with a long pedigree: module = import(modname, None, None, 'python2.4 is silly, revisit this line in 2.5')

I think that line in a code base of mine didn't get altered until 2.6.something.

Hack-ily,
