Is there a complete trackback you could post?  Then nobody would
have to guess what your problem is.

Obviously something is trying to access "yyy" before it actually
exists, so you must be missing something.  Do you have a circular
reference in xxx?  Are you aware that importing a module for the
first time actually causes any statements at module level to be
executed (which when the "def" and "class" statements are executed,
for example)?
