title: Appending list in lisp
body: <p>In lisp, I am appending lists as:
  (setq newlist (append (side a b)(this a b) (that a b) ))</p>
  
  <p>This appends all the required list as: (1 0 0 0 2 0 4 0 6 0)
  but what I want is something like this: ((1 0)(0 0)(2 0)(4 0)(6 0))</p>
  
  <p>What should I do to get the required format. Please post code examples in lisp.</p>
