Description:	In Python, assignment statements don't copy objects, and data structures don't actually contain objects. These two surprising facts have a lot of interesting consequences and are the reason behind many of Python's design decisions. In this talk, we'll explore the reference-like nature of Python's variables and objects, noting both the benefits and gotchas involved. Among other ideas, we'll see that in Python: - The word "change" is ambiguous - Copying is usually explicit - Infinitely recursive data structures aren't a concern - And tuples aren't always immutable During the process, we'll poke at our own mental model of Python and we'll get a bit pedantic at times. Join us to learn how in Python, it's pointers (or references, names, bindings, or aliases) all the way down. markdown
