Why does this meme persist!? Of course Python has variables, they just don't
work like C variables do. If you'd like
to know the details: http://nedbatchelder.com/text/names.html
Because Python's model is different enough that it usually makes thinking about it simpler to stay away from the word
'variable'; in every other language I have used a variable is a box, but in Python it's a label for a box.
From your blog:
Names are Python's variables: they refer to values, and
those values can change (vary) over the course of your
program.
This is partially incorrect. If the value referred to by the name is immutable, then it cannot change; perhaps you
meant to say that which object the name points to can vary over time?
