Hmm, the module thinks its name is "hello", but it's in Test.DLL?
Maybe it should be hello.pyd?

The .pyd is to designate it as a Python extension. Python stopped
importing plain .dlls along about Python 2.5.

As 'import Test' or as 'import hello'?

You said you wrote a wrapper class, and that the add, sub etc. are
methods on that class?

Let's say your wrapper class is called Wrapper.

import hello
obj = hello.Wrapper()  # instantiate

-- or, equivalently --

from hello import Wrapper
obj = Wrapper()

-- then, either way --

print obj.add(something, something_else)
