Look again at the documentation for __import__. In particular, you
want a function like the following, given in the dicumentation:

def my_import(name):
    mod = __import__(name)
    components = name.split('.')
    for comp in components[1:]:
        mod = getattr(mod, comp)
    return mod

Then, you do

    eggs = my_import("spam.eggs")

I have to admit, I find this annoyingly subtle - 99.99% of the time,
it's my_import() that you want, but you have to define it yourself...

Ah, well. I hope this helps.
