DESCRIPTION:In Python\, assignment statements don't copy objects\, and data
  structures don't actually contain objects. These two surprising facts hav
 e a *lot* of interesting consequences and are the reason behind many of Py
 thon's design decisions.\n\nIn this talk\, we'll explore the reference-lik
 e nature of Python's variables and objects\, noting both the benefits and 
 gotchas involved.\n\nAmong other ideas\, we'll see that in Python:\n\n- Th
 e word "change" is ambiguous\n- Copying is usually explicit\n- Infinitely 
 recursive data structures aren't a concern\n- And tuples aren't always imm
 utable\n\nDuring the process\, we'll poke at our own mental model of Pytho
 n and we'll get a bit pedantic at times.\n\nJoin us to learn how in Python
 \, it's pointers (or references\, names\, bindings\, or aliases) all the w
 ay down.
