Thank you all for your replies. When I do a

from Univariate import Univariate

the TypeError disappears and everything is fine.  Clearly this was an error that a newbie such as myself is likely to make because of little experience with Python. However, this isn't something I'm likely to forget.

I will also adopt the style recommendations.  Thanks, again.
