I really don't understand what are you missing.
Please post an example of what you want and an example on where you are
stuck.
PS: if "thesomething" you want to print comes as a result from a function,
why is difficult to do
def afunction(a, b):
return a + b
def yourcontroller():
thesomething = afunction(4,5)
response.menu.append(
(thesomething, False, URL('bla bla'))
)
return dict()
