As a beginner, I found that it was useful to note how these 2 approaches
differ. In the first approach:
a = Univariate.Univariate(foo)
what you're doing is loading everything in Univariate in a separate
namespace (the Univariate namespace). The other approach:
from Univariate import Univariate
a = Univariate(foo)
what you're doing is loading *just* Univariate into your top level
namespace. It's important to note this difference because it has
potentially critical implications as far as clobbering existing functions
that happen to have the same name (if you're loading into your top level
namespace with, for instance, "from mymodule import *") versus keeping
everything in a separate namespace so stuff doesn't get overwritten.
This is more applicable to scripts/programs you write that import a number
of different modules, all of whom may contain objects with the same name.
