Yeah; the default value is not reevaluated between calls. It's a common gotcha. Here are a few links to read more: http://effbot.org/zone/default-values.htm http://docs.python-guide.org/en/latest/writing/gotchas/#mutable-default-arguments Good luck!
Aha, the object that stores the default value for the optional argument is created at the time of the execution of the function definition and mutable objects do mutate, so that's that. It makes a lot of sense.
