In Python 101, you learned basic Python syntax. In Python 102 (or equivalent in experience), you went further, exploring Python more deeply, creating/using classes, methods, functions, decorators, files, modules/packages, and basically no longer a beginner. Because Python has been around the block for quite awhile now, there is a continuously growing number of existing “Python 103” programmers out there. Many are no longer new to the language, however, they have run into various issues, bugs, or odd behavior in their code that is difficult to explain. It’s time to take a closer look at Python. Think about questions like these:
SNIPPET A x = 42 y = x x += 1 print x print y
SNIPPET B x = [1, 2, 3] y = x x0 = 4 print x print y
This talk is primarily focused on discussing at an in-depth level, how Python’s object model and memory management works. We’ll also look at best practices such as thinking about performance, “useful” commenting, and other related topics. Time-permitting, we will have a “town hall” Q&A session where attendees bring up their issues and let the audience chime in with possible solutions.
Knowing more about how the interpreter works under the covers, including the relationship between data objects and memory management, will make you a much more effective Python programmer, and the (main) goal with the knowledge imparted in this talk is to empower developers to not (inadvertently) create certain classes of bugs in their code to begin with! All you need to bring is the desire to learn more about the interpreter to take your Python skills to the next level.
