Someone already mentioned lambda expressions, which should work if your
function is just a simple thing.  If if you are creating alot of these
little functions and they all follow a certain pattern, you might want to
write a class and define it's __call__(self, ...)  method.  Then you could

callFunction( CallableObject(args) )
