Lists in Python versus other languages

  Well, you could say that, in LISP, the dotted pair

( 1 . ( 2 . NIL ))

  represents the list (1 2) while

( 1 . 2 )

  represent the tuple "1,2".

|but they're essentially arrays also.

  On an implementation level, an array is cache-friendly, while
  a linked list is not. LISP lists are linked lists, not arrays.

  In Python, the ast module can yield the structure of a module
  of Python code (including list and tuple literals) without
  the need to execute that code.
