Just use

funcvar = func

(no quotes) and you're done. In python, 'everything is a name' (which points 
to an object). func is just a name pointing to a function object, and the 
assignment makes funcvar be a second name pointing to the same thing. Think 
of it as C pointers which do all referencing/dereferencing/memory management 
magically for you.
