Tim is correct and web2py is push but,
1) an action can call another action in the same controller
2) it is possible to write a controller like
def index():
return(functions=globals())
and a corresponding view that calls
{{=functions['myotherfunction']()}}
where myotherfuction is another action in the same controller.
I am not suggesting this is good practice. Just pointing out it is
possible.
