Well, let me point out in fact you return only one variable :-)
(And btw, you can construct lists much easier - no need for
a, b and append() :-)

To have easy access to a lot of names throughout your ZPT,
the usual pattern is to call your ZPT from controller
python script.

Like this:

a='yo'
b='wuzzup'

return context.yourZPT(a=a,b=b)

and in your ZPT you access the values simply by:

options/a  and options/b

this can be extended by using arbitrary nested dictionaries
(and lists for loops)

a=dict(name='peter',age=25)

return context.yourZPT(a=a)  # left hand 'a' is the name you use
                             # inside ZPT of course

and inside ZPT: options/a/name   options/a/age
