You're doing everything correctly, just not quite enough.
What you've got is an almost empty module named "spam",
which contains another module bound to the identifier "eggs".

So what you need to do is:

m = __import__("spam.eggs")
eggs = spam.eggs

This will probably also work:

eggs = __import__("spam.eggs").eggs
