See if I can get in first with the answer.

You're not calling the function unless you put () on the end.

So you need:

mytest.yo()

Otherwise you're just referencing the function. This is comon in a few
languages I can think of.

Why would you want to reference the function?

Consider:

func = mytest.yo
.
.
func()


Would also execute your function. Passing functions around is quite
handy sometimes.
