Ah, right, different problem. There's much to be said and disputed about what makes a 10K program Pythonic; my oversimplification would be something like: - between half a dozen and two dozen files in 2-3 directory levels - lots of small classes with short methods - some short functions - lots of dictionaries - no God objects - some comprehensions, generators, and decorators - about 2-4 levels of abstraction between the problem statement and the core routines in inner loops - pivot away from any of the above if the problem calls for it, but many problems don't

Even simpler: if you're writing short callables (functions/methods, mostly) and using them as the values in dictionaries, you're most of the way to writing intermediate Python.
