What I do in such cases is--
In the controller C.py,
def myController1():
return dict()
for returning a dict, I write a script
def getDict():
do the processing...
D={key:value pairs go here}
return response.json(D)
In myController.html View file,
...
access D by using {{=URL('app','C','getDict')}}
Then parse D for whatever the purpose.
I think this detaches the server side function 'getDict' from the main
function 'myController1'.
