Python tips, tricks, and idioms

Using syntax well: slices, tuple unpacking, for-else, for-break.
Take advantage of language dynamics: introspection, bound methods, and getattr()
Non-java python: duck-typing, abstract base classes, easier-to-ask-forgiveness, and super().
Using iteration as glue: iterator pipelines, itertools, and generators.
Higher-level python: set(), sorted(), heapq, etc.
