I have created a list of variables, myvars

I'd like to create a function of those variables, but

myvars = var('x y z')
 f = function('f')(myvars)

doesn't work.

Of course in my actual code I'm creating myvars programatically, so doing

 f = unction('f')(myvars[0], myvars[1], myvars[2])

is not convenient

You should use the star operator to unpack the tuple myvars, i.e. write the function argument as *myvars:

sage: myvars = var('x y z')
sage: f = function('f')(*myvars)
sage: f
f(x, y, z)
