Attack of Pythons: Gotchas and Landmines in Python

Python is friendly until it isn’t. A live tour of the language’s surprising corners: mutable default arguments, late-binding closures, integer caching, is versus ==, floating-point traps, and the odd behaviours of datatypes and syntax that bite even experienced developers. Every example runs in front of the room, the reason is revealed afterwards. I gave this one in six countries over three years.
