Python Names and Values
This is a presentation I gave at PyCon 2015 in Montreal. You can read the slides and text on this page, or open the actual presentation in your browser (use right and left arrows to advance the slides). The figures in the presentation are animated, which you won’t see on this page, click through the presentation to see them in their full glory. You can also watch the video of me presenting it:
Also, this is a re-working of an earlier piece with the same name: Facts and myths about Python names and values. It covers the same ideas, but with different text and figures.
Python is a very approachable language. Often it works just as you expect if you come to it from other languages. But you might suddenly encounter surprising behavior.
The underlying mechanisms of Python are often quite simple, but their combined effects might not be what you expect. By understanding the mechanisms, you can reason about their effects.
