Array Literal Representation

• A list or array literal is created with a comma delimited list of scalars enclosed in parenthesis.
• Each scalar forms the elements in the list (array), in the same order.
• Example:
  

  (20, 21, 22,) # Array of three numbers, 20, 21, and 22 
  ("a string", 2, 3, "another string") # Array of mixed nums and strings 
  () # The empty list.
